6. What is the total number of valence electrons in an
atom of germanium in the ground state?

4⁺

Explanation:

Germanium (Ge) has an atomic number of 32 and belongs to group 14 on the periodic table. Germanium has an electronic configuration of [Ar] 3d¹⁰ 4s² 4p². There exist 32 electrons in its neutral atom. In fluorescent lights, germanium is utilized as a component of both alloys and phosphorus.

The electrons in the atom's outer shell are known as its valence electrons.

Thus, at the ground state, the outer shell of the Germanium atom has 4 electrons.
