Question
How do you calculate the possible valency of an element from the electronic configuration of its atoms?
Solution
The electrons present in the last shell determine the valency of a particular element.
If, Number of valence electrons ≤4: valency = number of valence electrons Number of valence electrons >4: valency = 8 - number of valence electrons
