Valence Electrons

Postby Mulin_Li_2J » Sun Nov 03, 2019 11:46 pm

A general definition of valence electrons is number of electrons existed in the out-most shell of the atom. But does this definition really apply to transitional metals? Because if it does, Cu will technically have 11 valence electrons.

Writing out the electron configuration for Cu, there is one valence electron: [Ar] 3d10 4s1

Since the outermost shell of Cu only has one electron in 4s1, then there is only 1 valence electron.
