Solution

The correct option is A 4
The valence electrons are the electrons present in the outermost orbit.

For an element having an electronic configuration (2,8,4), the number of valence electrons are 4.

If the number of valence electrons of the atom of an element is 4 or less,
Valency = Number of valence electrons

Therefore, valency = 4
