Solution

S.No Element Name Electronic configuration Valance electron Valency
1 Na Sodium 2,8,1 1 1
2 Al Aluminum 2,8,3 3 3
3 Ca Calcium 2,8,8,2 2 2
4 Ne Neon 2,8 8 0
Valance electrons are the electrons present in outermost shell
Valency of an atom can be determine as Follow
(a) If valence electrons are â‰¤ 4, then valency = valance electron
(b) If valence electrons are > 4, then valency = 8- valance electron.
