Germanium has 32 electrons per atom. 4 of those are valence electrons. Thus, germanium has 28 core electrons. Germanium has 32 electrons per atom. 4 of those are valence electrons.
As we go from fluorine to neon to sodium, the number of valence electrons increases from 7 to 8 and then drops down to 1 when we start the new period with sodium. Within a group--starting with carbon and going down to silicon and germanium--the number of valence electrons stays the same.
