Answer 1

Valence electrons are the electrons that are located in the outermost electron shell. Knowing how to find the number of valence electrons in a particular atom is an important aspect. Luckily, all you need to find is an important element's valence electrons is a standard periodic table of the elements.

The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. The valency is equal to eight minus the number of electrons in the outer shell. you can calculate the valency without any trouble once you know the number of electrons

Answer 2

The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.
