Answer 2

The number of valence electrons present in a metal atom is its valency.

• The valency of a metal atom is defined as the total number of valance electrons present in it.
• For example, the electronic configuration of sodium metal or Na metal is given as follows-
• ${1s}^{2} {2s}^{2} {2p}^{6} {3s}^{1}$
• Thus Na has one valance electron so, its valency is one.
• Hence the correct option is c.
