Question

The valence electrons of a germanium atom in the ground state are located in the

(1) first shell (3) third shell
(2) second shell (4) fourth shell

Answer 1

The valence electrons of a germanium atom in the ground state are located in the Fourth shell.

Answer 2

Ge atomic number is 32 and the condensed electron configuration is -

[Ar] 3d¹⁰ 4s² 4p²

valence electrons are electrons in the outermost energy shell involved in chemical bonding

the number of electrons in the 4th energy shell are 4 electrons

according to the definition valence electrons are electrons in the outermost energy shell

the outermost energy shell of Ge is the 4th energy shell

therefore

The valence electrons of a germanium atom in the ground state are located in the

(4) fourth shell
