Solution
The number of electrons that an atom needs to lose or gain in order to achieve a stable electron configuration is known as the valency of an element, which serves as a gauge of that element's potential for combining.
Sodium () has an atomic number of 11, and its electronic configuration is:
Hence, the valence of Sodium with atomic number 11 is 1.
