Updated: 6/3/2024

Sodium has a valency of 1 because it donates 1 electron to achieve a stable octet configuration, forming a +1 ion. Chlorine has a valency of 1 because it gains 1 electron to achieve a stable octet configuration, forming a -1 ion. When they combine in a 1:1 ratio to form sodium chloride, the compound is electrically neutral.
