4d1. Some elements exist in several different structural forms, called allotropes. At present, though, there are technical problems preventing these commercial applications. Density is the mass of a substance that would fill 1 cm3 at room temperature. Similar to LFP, LYP batteries offer high energy density, good safety and long life. There are many possible applications for YBCO; for example MRI scanners could be made to operate more cheaply at a higher temperature using liquid nitrogen coolant. "This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features," the study reads. Concept: Formation and Properties of Ionic Compounds The chemical symbol for Yttrium is Y. Neutron Number and Mass Number of Yttrium Mass numbers of typical isotopes of Yttrium are 89. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. 1 2 3 The number of protons and neutrons is the same. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Group Yttrium has no known biological role. The real element 117 is yet to be discovered - it's a blank space in the Periodic Table just below the halogens. Anion Y - has one more electron than its neutral atom. Yttrium is a chemical element with the symbol Y and atomic number 39. Sublimation What is known is that the composition of the copper-oxide materials must be precisely controlled for superconductivity to occur. [12][6][i] The red color itself is emitted from the europium while the yttrium collects energy from the electron gun and passes it to the phosphor. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction. A few of these are known to have yttrium in the oxidation state 0. Atomic number The number of protons in an atom. Density: 4.47 grams per cubic centimeter 7. You're listening to Chemistry in its element brought to you by. A reason - it is on left side of periodic table and has three valence electrons - so Y+1 with a 5s2 valence situation OR Y+3 to get back to being isoelectronci with Kr are favored. Schematic electronic configuration of yttrium. Each allotrope has different physical properties. Text © The Royal Society of Chemistry 1999-2011 Comprehensive data on the chemical element Yttrium is provided on this page; including scores of properties, element names in many languages, most known nuclides of Yttrium. [27] Yttrium isotopes with mass numbers at or above 90 decay primarily by electron emission (neutron → proton) to form zirconium (Z = 40) isotopes. You do not have JavaScript enabled. In 1843, Carl Mosander investigated yttrium oxide more thoroughly and found that it consisted of three oxides: yttrium oxide, which was white; terbium oxide, which was yellow; and erbium oxide, which was rose-coloured. The ultimate objective, the Holy Grail, is to find a material that would superconduct at room temperature, but no one has got there yet. Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. 150–152. [25] The r-process consists of rapid neutron capture by lighter elements during supernova explosions. The temperature of an arc furnace of greater than 1,600 °C is sufficient to melt the yttrium.[46][60]. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative than lanthanum, but less electronegative than lutetium due to the lanthanide contraction. Click on 'Element Atomic Number', 'Element Symbol', 'Element Name' and 'Element Valence Electrons' headers to sort. Yttrium Element: Yttrium is a chemical element and it is a member of group 3 and period 5 in the periodic table. All group 3 elements have an odd atomic number, and therefore few stable isotopes. Y3(Fe,Al)5O12 and Y3(Fe,Ga)5O12) have important magnetic properties. Medium = substitution is possible but there may be an economic and/or performance impact, Low = substitution is possible with little or no economic and/or performance impact, If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department. LYP cells have essentially same nominal voltage as LFP, of 3.25V, and very similar charging and discharge characteristic. However, the BCS theory does not explain high temperature superconductivity, and its precise mechanism is still a mystery. Murray Robertson is the artist behind the images which make up Visual Elements. Yttrium oxide and iron oxide combine … The oxidation state of an atom is a measure of the degree of oxidation of an atom. He thought he had found a new tungsten mineral, and passed the specimen over to Johan Gadolin based in Finland. The radioactive microspheres are delivered directly to the blood vessels feeding specific liver tumors/segments or lobes. The atomic number of each element increases by one, reading from left to right. Yttrium is a key ingredient in the yttrium barium copper oxide (YBa2Cu3O7, aka 'YBCO' or '1-2-3') superconductor developed at the University of Alabama and the University of Houston in 1987. The number of electrons in each of yttrium's shells is 2, 8, 18, 9, 2 and its electron configuration is [Kr] 4d 1 5s 2.The yttrium atom has a radius of 177.6.pm and its Van der Waals radius is 200.pm. All such documents and related graphics are provided "as is" without any representation or endorsement made and warranty of any kind, whether expressed or implied, including but not limited to the implied warranties of fitness for a particular purpose, non-infringement, compatibility, security and accuracy. Electron emission of isotopes with those mass numbers is simply less prevalent due to this stability, resulting in them having a higher abundance. 5s2 and the term symbol is 2D3/2. [62] Yttrium compounds can serve as host lattices for doping with different lanthanide cations. [12] Cerium-doped yttrium aluminium garnet (YAG:Ce) crystals are used as phosphors to make white LEDs. It is also used to make superconductors. Yttrium metal of 99.9% purity is commercially available at a cost of about $75/oz. In such cases we would ask you to sign a Visual Elements licence agreement, tailored to the specific use you propose. [49], Since yttrium is chemically so similar to the lanthanides, it occurs in the same ores (rare-earth minerals) and is extracted by the same refinement processes. [6] The carbides Y3C, Y2C, and YC2 can be hydrolyzed to form hydrocarbons. A horizontal row in the periodic table. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Allotropes The ground state electronic configuration of neutral yttrium is [Kr].4d 1.5s 2 and the term symbol of yttrium is 2 D 3/2.. Yttrium: description Your user agent does not support the HTML5 Audio element. Electrons have a specific form of distribution (or configuration) in every atom, even Yttrium. An n − t y p e semiconductor is formed by doping pure germanium or silicon crystal with suitable impurity atoms of valency five. We hope that you enjoy your visit to this Site. Such materials are used in the "cool white" fluorescent lamps. Name: Yttrium Symbol: Y Atomic Number: 39 Atomic Weight: 88.905850 Family: Transition Metals CAS RN: 7440-65-5 Description: Silvery metal, which is stable in air because of an oxide film that forms on its surface. The name is historical and comes from the village of Ytterby, in Sweden where, in 1787, the chemist Arrhenius found a new mineral and named it ytterbite. Atomic Symbol Y Sources Found in minerals such as monazite, xenotime, and yttria. What is the abbreviated electron configuration of yttrium (Y) [Kr]5s^24d^1. Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. [36][37][38], In 1843, Carl Gustaf Mosander found that samples of yttria contained three oxides: white yttrium oxide (yttria), yellow terbium oxide (confusingly, this was called 'erbia' at the time) and rose-colored erbium oxide (called 'terbia' at the time). [12] Having a high melting point, yttrium oxide is used in some ceramic and glass to impart shock resistance and low thermal expansion properties. If you wish to use the Images in a manner not permitted by these terms and conditions please contact the Publishing Services Department by email. [39][40] A fourth oxide, ytterbium oxide, was isolated in 1878 by Jean Charles Galissard de Marignac. Atoms of the same element with different numbers of neutrons. [g][33][34][35], Friedrich Wöhler is credited with first isolating the metal in 1828 by reacting a volatile chloride that he believed to be yttrium chloride with potassium.

Atomic number (number of protons in the nucleus): 38 2. High = substitution not possible or very difficult. [65], Currently under development is yttrium-stabilized zirconia as a solid electrolyte and as an oxygen sensor in automobile exhaust systems. Number of Protons: 70: Number of Neutrons: 103: Number of Electrons: 70: Melting Point: 824.0° C: Boiling Point: 1466.0° C: Density: 6.98 grams per cubic centimeter: Normal Phase: Solid: Family: Rare Earth Metals: Period: 6: Cost: $530 per 100 grams . Yttrium's atomic number is 39. CAS number A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators. [8][9][10] Yttrium is the first d-block element in the fifth period. [42] In the following decades, seven other new metals were discovered in "Gadolin's yttria". This procedure may not eliminate all tumors throughout the entire liver, but works on one segment or one lobe at a time and may require multiple procedures.[78]. The leading countries for these reserves included Australia, Brazil, China, India, and the United States. [7] Workers exposed to airborne yttrium europium vanadate dust experienced mild eye, skin, and upper respiratory tract irritation—though this may be caused by the vanadium content rather than the yttrium. Download our free Periodic Table app for mobile phones and tablets. The number of protons and electrons is the same. The chemical symbol for Yttrium is Y. Yttrium is an element that's symbol is Y and has the number 39. Some people might just have known that it was one of 4 chemical elements named after the small Swedish town of Ytterby, along with ytterbium, erbium and terbium. [27][d] Multiple excitation states have been observed for 80Y and 97Y. These monitor the amount of oxygen in the exhaust gases and sends feedback to give the best air-fuel mixture into the engine. [43], In 1987, yttrium barium copper oxide was found to achieve high-temperature superconductivity.

The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Our yttrium page has over 200 facts that span 92 different quantities. 1 Predict the charge on the most common monatomic ion formed by each element. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. [8] Scandium has one stable isotope, and yttrium itself has only one stable isotope, 89Y, which is also the only isotope that occurs naturally. The tendency of an atom to attract electrons towards itself, expressed on a relative scale. And erbium gives you an infrared laser. It was called an’ earth’ because it was yttrium oxide, Y. [46] Yttrium is found in soil in concentrations between 10 and 150 ppm (dry weight average of 23 ppm) and in sea water at 9 ppt. The temperature at which the liquid–gas phase change occurs. [26][b] Such a slow process tends to favor isotopes with atomic mass numbers (A = protons + neutrons) around 90, 138 and 208, which have unusually stable atomic nuclei with 50, 82, and 126 neutrons, respectively. 12–13). It increases the strength of aluminium and magnesium alloys. [22]) Some trimerization reactions were generated with organoyttrium compounds as catalysts. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Yttrium-89 is thought to be more abundant than it otherwise would be, due in part to the s-process, which allows enough time for isotopes created by other processes to decay by electron emission (neutron → proton). Yttrium also finds use in fuel cells for powering cars and buses, computers and digital phones and, potentially, buildings. As such yttrium compounds such as yttrium aluminium garnet (YAG) are useful for phosphors and are an important component of white LEDs. [12] The addition of yttrium to alloys generally improves workability, adds resistance to high-temperature recrystallization, and significantly enhances resistance to high-temperature oxidation (see graphite nodule discussion below). The radar reflects the use of yttrium in radar technology. Apart from this, there are lots of everyday applications for yttrium compounds In its compounds yttrium is always present as the yttrium three plus ion, which means that it is colourless and has no unpaired electrons; therefore it does not have any interesting magnetic or spectroscopic properties of its own. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons. The radioactive isotope yttrium-90 has medical uses. Ion absorption clays or Lognan clays are the weathering products of granite and contain only 1% of REEs. [48] Yttrium can be found in edible plants in concentrations between 20 ppm and 100 ppm (fresh weight), with cabbage having the largest amount. In 2009, Professor Mas Subramanian and associates at Oregon State University discovered that yttrium can be combined with indium and manganese to form an intensely blue, non-toxic, inert, fade-resistant pigment, YInMn blue, the first new blue pigment discovered in 200 years. Until about 20 years ago, most scientists had not heard of it, other than vaguely noting where it was in the periodic table, under scandium and above lanthanum. LYP batteries do find use in stationary applications (off-grid solar systems), electric vehicles (some cars), as well other applications (submarines, ships), similar to LFP batteries, but often at improved safety and cycle life time. [56] The single crystals of doped YAG are normally produced by the Czochralski process. The availability of suitable substitutes for a given commodity. Yttrium's stable isotope is 89Y, which has 89 - 39 = 50 neutrons. [11], Yttrium in the Solar System was created through stellar nucleosynthesis, mostly by the s-process (≈72%), but also by the r-process (≈28%). It can be used to treat some cancers, such as liver cancer. [12] As a metal, yttrium is used on the electrodes of some high-performance spark plugs. The percentage of a commodity which is recycled. It is mined in China and Malaysia. This is made of yttrium oxysulphide, Y2O2S containing a small amount of trivalent europium ions. Images © Murray Robertson 1999-2011 The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. The most important uses of yttrium are LEDs and phosphors, particularly the red phosphors in television set cathode ray tube displays. These values were determined using several different methods. Yttrium Y Element 39 Mass Number: 89 Atomic weight: 88.905 g/mol Atomic number (Z): 39 Electrons: 39 Protons: 39 Neutrons: 50 Period: 5 Group: 3 Block: d Atomic Number of Yttrium. That number is equal to the number of protons. The percentage of the world reserves located in the country with the largest reserves. A slight distinction is recognized between the light (LREE) and the heavy rare-earth elements (HREE), but the distinction is not perfect. [48] With as much as 700 ppm, the seeds of woody plants have the highest known concentrations. The atomic number of each element increases by one, reading from left to right. We welcome your feedback. Y is the symbol for the element yttrium. The electrons in the outermost shell of an atom are called: valence electrons The valence electrons of an atom are those in the outermost shell, which are available for bonding or ionization. [47] Normally, as little as 0.5 milligrams is found in the entire human body; human breast milk contains 4 ppm. [7] The Occupational Safety and Health Administration (OSHA) limits exposure to yttrium in the workplace to 1 mg/m3 over an 8-hour workday. The following rules are followed for writing the number of electrons in different energy levels or shells: The maximum number of an electrons present in a shell is given by formula 2n 2, where ‘n’ is the orbit number or energy level index 1,2,3 … Hence, the maximum number of electrons in different shells are as: In first orbit or K-shell (n=1) = 2 * N 2 = 2 * 1 2 = 2. Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 3. [h], Yttrium is found in most rare-earth minerals,[9] it is found in some uranium ores, but is never found in the Earth's crust as a free element. Values are given for typical oxidation number and coordination. Where more than one isotope exists, the value given is the abundance weighted average. Each allotrope has different physical properties. Boiling point Description Silvery, ductile, fairly reactive metal. Bengt Geijer, the inspector of mines in Stockholm, carried out a rough analysis of ytterbite. A Yttrium is in group 3, and elements in this group are metals that tend to lose electrons. Atomic number A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ). But LYP, offer higher cathode stability, and prolong life of battery, by protecting physical structure of the cathode, especially at higher temperatures and higher charging / discharge current. [32] In the decades after Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. An integrated supply risk index from 1 (very low risk) to 10 (very high risk). Elements are organised into blocks by the orbital type in which the outer electrons are found. [7], Water-soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. The metal readily reacts with diluted [23][24], Hapticity is a term to describe the coordination of a group of contiguous atoms of a ligand bound to the central atom; it is indicated by the Greek character eta, η. Yttrium complexes were the first examples of complexes where carboranyl ligands were bound to a d0-metal center through a η7-hapticity. [69][70][71], YAG, yttria, yttrium lithium fluoride (LiYF4), and yttrium orthovanadate (YVO4) are used in combination with dopants such as neodymium, erbium, ytterbium in near-infrared lasers. [46], The radioactive isotope yttrium-90 is used in drugs such as Yttrium Y 90-DOTA-tyr3-octreotide and Yttrium Y 90 ibritumomab tiuxetan for the treatment of various cancers, including lymphoma, leukemia, liver, ovarian, colorectal, pancreatic and bone cancers. It is based on a peculiarity of the interaction between two electrons in a crystal lattice. This may not seem much of a temperature difference, but it meant that YBCO could be kept in the superconducting state using liquid nitrogen, rather than the much more expensive liquid helium. [75] Yttrium is used to increase the strength of aluminium and magnesium alloys. [11], Water readily reacts with yttrium and its compounds to form Y2O3. The yttrium.
