The atomic number of an element X is 16.
(a) Write down the electronic configuration of X.
(b) What will be the valency of X?

Open in App

Solution

(a) Electronic configuration of X = 2, 8, 6.

(b) Valency is the number of electrons participating in bond formation.
So, here X requires two electrons to attain noble gas configuration, so it will share 2 electrons with other elements and form a bond.
