The chemical symbol for Barium is Ba. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. Chemically, indium is similar to gallium and thallium.  It is a synthetic element (first synthesised at Hasse in Germany) and radioactive. The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The chemical symbol for Indium is In. Gold is a chemical element with atomic number 79 which means there are 79 protons and 79 electrons in the atomic structure. The Cookies Statement is part of our Privacy Policy. Thorium is commonly found in monazite sands (rare earth metals containing phosphate mineral). Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u. On the periodic table of the elements, atomic radius tends to increase when moving down columns, but decrease when moving across rows (left to right). Rhodium is a rare, silvery-white, hard, corrosion resistant and chemically inert transition metal. The chemical symbol for Thulium is Tm. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. This dependence is usually expressed by the coefficient of linear or volume expansion. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. Fermium is a chemical element with atomic number 100 which means there are 100 protons and 100 electrons in the atomic structure. A higher concentration can taste bitter or salty. In a neutral atom there are as many electrons as protons moving about nucleus. Therefore, the effective nuclear charge towards the outermost electrons increases, drawing the outermost electrons closer. Under standard conditions, it is the lightest metal and the lightest solid element. It is even less abundant than the so-called rare earths. The chemical symbol for Germanium is Ge. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. 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. Copyright © 1996-2012 Yinon Bentor. The chemical symbol for Dysprosium is Dy. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Copper is a chemical element with atomic number 29 which means there are 29 protons and 29 electrons in the atomic structure. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. It also reacts with many other elements and substances such as oxygen, acids, sulfur, fluorine, and nitrogen. Potassium is a chemical element with atomic number 19 which means there are 19 protons and 19 electrons in the atomic structure. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons and 66 electrons in the atomic structure.

Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. At 0.099%, phosphorus is the most abundant pnictogen in the Earth’s crust. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.

Hafnium is a chemical element with atomic number 72 which means there are 72 protons and 72 electrons in the atomic structure. This effect is caused by a decrease in the atomic number density. Lawrencium is the final member of the actinide series. Potassium is the … Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure.
