➡️ In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Answer 2

Answer:

Valence electrons - The number of electrons present in the outermost shell ( which is also known as Valence Shell ) is known as Valence electrons .

Let us know more -

♦ What is valency -

→Valency is the combining capacity of an element which further decides its degree of participation in a chemical reaction.

♦ An electron has various shells like K, L, M, N to accomodate electrons .The outermost shell decides the Valency and electrons present in that shell are termed as Valence Electrons , which generally take part in chemical reactions .
