Valence electrons

Postby Kyle Harvey 4F » Sun Oct 20, 2019 3:13 pm

When looking at an electron configuration, such as Chromium [Ar] 3d^5 4s^1, would the valence electrons be considered all the electrons in the 3d and 4s state? Or would the valence electrons be the ones in the 3d state?

The valence electrons of chromium include both its 4s and 3d electrons so it has 6 valence electrons in total.

For chromium the valence electrons would be both the electrons in the 4s and 3d state because chromium has 6 valence electrons.

You would have to include both the 4s orbital and 3d orbital in your count for valance electrons. Valance electrons determine the amount of bonds that is possible for the atom so since you have empty orbitals, they count towards your valance electron count.

The valence electrons include both because valence electrons mean all electrons in the outer shell.
