Chemical Properties of Yttrium. [48], As of April 2018[update] there are reports of the discovery of very large reserves of rare-earth elements on a tiny Japanese island. Allotropes Smith's 117, however, was a strange material that could be used to open a window to another dimension. [12] As a metal, yttrium is used on the electrodes of some high-performance spark plugs. [42] In the following decades, seven other new metals were discovered in "Gadolin's yttria". Please enable JavaScript to access the full features of the site. This week, the last of the elements discovered in the small town of Ytterby and its compounds appear to have a multitude of uses. Question 13. [64] Yttrium is used in gas mantles for propane lanterns as a replacement for thorium, which is radioactive. Atomic Symbol Y Sources Found in minerals such as monazite, xenotime, and yttria. 39 protons and 39 electrons. Yttrium is the first d-block element in the fifth period. Melting point: 2,772 Fahrenheit (1,522 Celsius) 5. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. He reported that the miner… Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals. 2,8,18,9,2 Discoverer. [6] Yttrium is so close in size to the so-called 'yttrium group' of heavy lanthanide ions that in solution, it behaves as if it were one of them. Bednorz and Müller won the Nobel Prize for Physics in 1987 for this discovery. State at room temperature: Solid The sum of the oxidation states within a compound or ion must equal the overall charge. It is quite stable in air; rapid oxidation begins above approximately 450 °C (840 °F), resulting in Y2O3. Click on 'Element Atomic Number', 'Element Symbol', 'Element Name' and 'Element Valence Electrons' headers to sort. The availability of suitable substitutes for a given commodity. A few of these are known to have yttrium in the oxidation state 0. D Y is in the same period of the Periodic Table as X 28 Na,Which statements about a sodium atom, 23 11 are correct? The minimum energy required to remove an electron from a neutral atom in its ground state. Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 3. [50][51], Rare-earth elements (REEs) come mainly from four sources:[52]. It is defined as being the charge that an atom would have if all bonds were ionic. [46] Lunar rock samples collected during the American Apollo Project have a relatively high content of yttrium. transition metal. A vertical column in the periodic table. Yttrium oxide is added to the glass used to make camera lenses to make them heat and shock resistant. 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.

[12] Those same properties make such glass useful in camera lenses. Each entry has a full citation identifying its source. Yttrium also finds use in fuel cells for powering cars and buses, computers and digital phones and, potentially, buildings. So, that is yttrium for you. This Valence Electrons chart table gives the Valence Electrons of all the elements of periodic table . He thought he had found a new tungsten mineral, and passed the specimen over to Johan Gadolin based in Finland. The atomic number of each element increases by one, reading from left to right. [46][61] Global reserves of yttrium oxide were estimated in 2014 to be more than 500,000 tons. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. The National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit (REL) is 1 mg/m3 over an 8-hour workday. [82] Major manufacturer of LFP batteries is Shenzhen Smart Lion Power Battery Limited, with brands Winston and Thunder Sky.[83]. The RSC maintains this Site for your information, education, communication, and personal entertainment. Members of a group typically have similar properties and electron configurations in their outer shell. 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. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. Date discovered. The temperature at which the solid–liquid phase change occurs. Values are given for typical oxidation number and coordination. Exposure to yttrium compounds can cause lung disease in humans.[7]. The chemical symbol for Yttrium is Y. Neutron Number and Mass Number of Yttrium Mass numbers of typical isotopes of Yttrium are 89. Exercise 2.11. 12–13). High = substitution not possible or very difficult. Atomic Number of Yttrium. This film can reach a thickness of 10 µm when yttrium is heated to 750 °C in water vapor. [12] YIG is also very efficient as an acoustic energy transmitter and transducer. In 1787, Karl Arrhenius came across an unusual black rock in an old quarry at Ytterby, near Stockholm. The oxidation state of an atom is a measure of the degree of oxidation of an atom. To find the number of neutrons, subtract the element’s atomic number from its atomic mass (the number listed underneath the element). [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). [68] Yttrium aluminium garnet (Y3Al5O12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated diamond). The description of the element in its natural form. pp. [56] The single crystals of doped YAG are normally produced by the Czochralski process. Elements are shown from atomic number 1 (hydrogen) up to 94 (plutonium). You may not further copy, alter, distribute or otherwise use any of the materials from this Site without the advance, written consent of the RSC. [60] When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase. 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. 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. 4d1. And erbium gives you an infrared laser. In 1794, Gadolin announced that it contained a new 'earth' which made up 38 per cent of its weight. Yttrium Properties. This has inspired lots more studies over the past 20 years. Yttrium is a Block D, Group 3, Period 5 element. [6] The carbides Y3C, Y2C, and YC2 can be hydrolyzed to form hydrocarbons. Density: 4.47 grams per cubic centimeter 7. Atomic number (number of protons in the nucleus): 38 2. Xenotime can contain up to 50% yttrium phosphate. Researchers are studying a class of materials known as perovskites that are alternative combinations of these elements, hoping to develop a practical high-temperature superconductor. [67] Yttrium, iron, aluminium, and gadolinium garnets (e.g. Murray Robertson is the artist behind the images which make up Visual Elements. [48] With as much as 700 ppm, the seeds of woody plants have the highest known concentrations. It is used to make hard, artificial diamonds, which sparkle just like the real ones. Electrons have a specific form of distribution (or configuration) in every atom, even Yttrium. [27], Yttrium isotopes with mass numbers at or below 88 decay primarily by positron emission (proton → neutron) to form strontium (Z = 38) isotopes. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators. Atomic mass: 88.906 4. ●Number of protons in Yttrium(Y) is 39.Protons are present in the nucleus of Yttrium(Y). And Hayley Birch will be revealing the truth about such mythical monopoles in next week's Chemistry in its Element. The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars. Yttrium Electrons per Shell 2,8,18,9,2 Atomic Number 39 Learn more about the atomic number. Yttrium atoms have 39 electrons and the shell structure is 2.8.18.9.2. The RSC has been granted the sole and exclusive right and licence to produce, publish and further license the Images. [44] It was only the second material known to exhibit this property,[44] and it was the first-known material to achieve superconductivity above the (economically important) boiling point of nitrogen. The exact amount is crucial, and tricky to achieve. [65], Currently under development is yttrium-stabilized zirconia as a solid electrolyte and as an oxygen sensor in automobile exhaust systems. [11] The Y3+ ion is colorless in solution because of the absence of electrons in the d and f electron shells. Atomic number In such cases we would ask you to sign a Visual Elements licence agreement, tailored to the specific use you propose. It is based on a peculiarity of the interaction between two electrons in a crystal lattice. Chemical symbol for Yttrium is Y. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. B The nearest noble gas to yttrium is krypton, so yttrium is predicted to lose three electrons to form Y 3+, which has the same number of electrons as krypton. 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. [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. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The metal readily reacts with diluted Each allotrope has different physical properties. [5] Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. Yttrium oxysulfide used to be widely used to produce red phosphors for old-style colour television tubes. [81], This superconductor is a black and green, multi-crystal, multi-phase mineral. A slight distinction is recognized between the light (LREE) and the heavy rare-earth elements (HREE), but the distinction is not perfect. It is also used in white LED lights. A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ). [72][73] YAG lasers can operate at high power and are used for drilling and cutting metal. It is mined in China and Malaysia. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. The red component of color television cathode ray tubes is typically emitted from a yttria (Y2O3) or yttrium oxide sulfide (Y2O2S) host lattice doped with europium (III) cation (Eu3+) phosphors.
