Synonym: Aluminum dysprosium europium strontium oxide, Europium and dysprosium doped strontium aluminum oxide, Long persistent blue-green phosphor Empirical Formula (Hill Notation): Sr 3.84 Eu 0.06 Dy 0.10 Al 14 O 25 In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides. Platinum is one of the least reactive metals. It is stable in air at room temperature even if it is slowly oxydized by oxygen. On the other hand, ice (solid H2O) is a molecular compound whose molecules are held together by hydrogen bonds, which is effectively a strong example of an interaction between two permanent dipoles. This dependence is usually expressed by the coefficient of linear or volume expansion. It could be part of the main body, but then the periodic table would be rather long and cumbersome. Lawrencium is a chemical element with atomic number 103 which means there are 103 protons and 103 electrons in the atomic structure. The most stable known isotope, 269Hs, has a half-life of approximately 9.7 seconds. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. Instead, it is often combined with other metals to make dysprosium alloys. Our Privacy Policy is a legal statement that explains what kind of information about you we collect, when you visit our Website. Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. Its properties are thus intermediate between those of chlorine and iodine. Typical densities of various substances are at atmospheric pressure. Didysprosium trioxide. Below the melting point, the solid is the more stable state of the two, whereas above the liquid form is preferred. Covalent bonds often result in the formation of small collections of better-connected atoms called molecules, which in solids and liquids are bound to other molecules by forces that are often much weaker than the covalent bonds that hold the molecules internally together. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Electron affinity can be either positive or negative value. The chemical symbol for Rubidium is Rb. Rising temperatures make the liquid expand in a liquid-in-tube thermometer and bend bimetallic strips. The chemical symbol for Iron is Fe. Density is defined as the mass per unit volume. It can react with acids to produce the corresponding dysprosium (III) salts: Mendelevium is a chemical element with atomic number 101 which means there are 101 protons and 101 electrons in the atomic structure.

The density of a material varies with temperature and pressure. Element Dysprosium (Dy), Group Not Applicable, Atomic Number 66, f-block, Mass 162.5. The chemical symbol for Terbium is Tb. The electronegativity of Dysprosium is: χ = 1.22. The chemical symbol for Gadolinium is Gd. In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. For example, it reacts with hydrochloric acid to form dysprosium trichloride. Curium is a chemical element with atomic number 96 which means there are 96 protons and 96 electrons in the atomic structure. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. Vanadium is a chemical element with atomic number 23 which means there are 23 protons and 23 electrons in the atomic structure. Dysprosium metal is a soft, lustrous-silver rare earth element (REE) that is used in permanent magnets due to its paramagnetic strength and high-temperature durability. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). Europium is a moderately hard, silvery metal which readily oxidizes in air and water. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. The chemical symbol for Osmium is Os. Ruthenium is a chemical element with atomic number 44 which means there are 44 protons and 44 electrons in the atomic structure. The chemical symbol for Bromine is Br. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. Uranium is a silvery-white metal in the actinide series of the periodic table. The chemical symbol for Samarium is Sm. The most important ores are monazite and bastnasite. Element Dysprosium - Dy. Note that, these points are associated with the standard atmospheric pressure. Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. Component Compounds.
