Question

56. What would be the valence electrons of 14Si, 16S, 32Ge respectively?

A. 4, 2,2
B. 4, 6,8
C. 4, 6,6
D. 4,6,4​

Answer 1

Answer: D. 4,6,4

Explanation:

The valence electron is the electron found in the outermost shell of an atom, and participates in bond formation.

For the following element, the valence electron can be noticed when we write the electronic configuration of each element.

Silicon = 1s2 2s2 2P6 3s2 3p2

Sulphur = 1s2 2s2 2P6 3s2 3p4

Germanium = 1s2 2s2 2P6 3s2 3p6 3d10 4s2 4p2
