Electron affinity of Dysprosium is 50 kJ/mol. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. 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. Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the world’s reserves. Osmium is the densest naturally occurring element, with a density of 22.59 g/cm3. The electron affinity was determined to 6583.6(6) cm-1by observing the onset of the process when W-ions in the \(5d^56s^2\)6S5/2ground state are photodetached producing neutral W atoms in the … Thallium is a soft gray post-transition metal is not found free in nature. Tungsten Affinity's reply: At Tungsten Affinity we strive to provide an excellent product and even better customer service. The chemical symbol for Oxygen is O. Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. It is a soft, silvery-white alkali metal. Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. The chemical symbol for Lithium is Li. Note that, ionization energies measure the tendency of a neutral atom to resist the loss of electrons. The chemical symbol for Gold is Au. However, nitrogen, oxygen, and fluorine do not follow this trend. Nickel belongs to the transition metals and is hard and ductile. The chemical symbol for Thallium is Tl. Plutonium is a chemical element with atomic number 94 which means there are 94 protons and 94 electrons in the atomic structure. Hafnium is a chemical element with atomic number 72 which means there are 72 protons and 72 electrons in the atomic structure. Electron Affinity of Tungsten is 78.6 kJ/mol. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. It is the heaviest essential mineral nutrient. The chemical symbol for Promethium is Pm. It is a noble metal and a member of the platinum group. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. It is even less abundant than the so-called rare earths. The chemical symbol for Barium is Ba. Welcome to Tungsten Affinity! Electronegativity of Tungsten is 2.36. Our tungsten page has over 400 facts that span 98 different quantities. Indium is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
