how to calculate the valency

Asked by Vijaya | 5th Oct, 2017, 03:14: AM

Expert Answer:

The valency of an atom is equal to the number of electrons in the outermost shell if that number is four or less.
If the number of electrons are more than four then the valency is equal to eight minus the number of electrons in the outer shell.
