Answer 1

Valence electrons:-

1. The number of electrons present in the valence shell or the outermost shell of an atom is known as valence electrons.
2. The number of valency electrons remains the same down the group and increases by 1 as we go across the period from left to right.

Hence, the electrons present in the outermost shell of an atom is called valence electrons.
