It is common that the three heaviest elements of the sulfur sub-group, namely selenium, tellurium, and polonium, be collectively referred to as the "chalcogens," and the term chalcogen be addressed only for these elements - in practice, only for the chemically and technologically important selenium and tellurium; however, according to the official guides to inorganic nomenclature, the ...Electron affinity is almost zero or low in elements having a stable electronic configuration. This is due to the small tendency to accept another electron. Electron affinities of inert gases are zero. This is due to their atoms having stable ns²np⁶ configuration in their shell. Electron affinity of Beryllium, and calcium is practically zero.
