How many core electrons are in germanium?

Answer 1

Germanium has 32 electrons per atom. 4 of those are valence electrons. Thus, germanium has 28 core electrons.

Answer 2

In germanium, the number of core electrons is equal to the number of electrons in its inner shells. The electron configuration of germanium is [Ar] 3d10 4s2 4p2, where [Ar] represents the electron configuration of argon. Therefore, germanium has 18 core electrons.
