Web26 nov. 2024 · Electron Affinity of Calcium is 2.37 kJ/mol. Electronegativity of Calcium is 1. Electron Affinity. 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. WebIt is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes Atoms of the same element with different numbers of neutrons. Key for isotopes Oxidation states and isotopes Glossary
