What is the total number of valence electrons in a germanium atom in the ground state? (1) 22 (3) 32 (2) 2 (4) 4

Answer is (4) - 4.

The atomic number of Germanium (Ge) is 32 and it is placed in 14th group of periodic table. In the neutral atom, 32 electrons are present. The electron configuration of Ge is [Ar] 3d¹⁰ 4s² 4p².

Valence electrons are the electrons which are in outer shell of the atom. There are 4 electrons in outer shell of Ge atom at ground state.

The total number of valence electrons in a germanium atom in the ground state is. 4.
