Cr electronegativity value

WebElectronegativity, symbol χ, is a chemical property which describes the power of an atom (or, more rarely, a functional group) to attract electrons towards itself. [1] First proposed by Linus Pauling in 1932 as a development of valence bond theory, [2] it has been shown to correlate with a number of other chemical properties. WebJan 3, 2024 · The electronegativity difference of Co 14 Cr 30 Ni 50 Mo 6 is 0.136, which is the highest value as predicted temperatures of phase decomposition are about 900 °C.
