Germanium has valence electrons and chlorine has valence electrons

Germanium has 4 valence electrons and chlorine has 7 valence electrons.

Explanation:

last shell of chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons present in an chlorine atom.

Solid state electronics arises from the unique properties of silicon and germanium, each of which has four valence electrons and which form crystal lattices in which substituted atoms (dopants) can dramatically change the electrical properties.
