Answer 2

Answer:

c) 1

Explanation:

Valency is the number of electron(s) required to gain or lose in the outermost shell to obtain an inert gas configuration. The atomic configuration of potassium is 2,8,8,1.

By losing the valence electron(1), potassium can achieve inert gas configuration.

Thus, the valency of potassium is 1.
