Detailed explanation-1: -Valence electrons, the electrons in the outermost or valence shell, are important as they provide insight into an element’s chemical properties and are the ones gained, lost, or shared during a chemical reaction. In general, atoms are most stable and least reactive when their outermost electron shell is full.

Detailed explanation-2: -Explanation: In any chemical reaction, only valence electrons participate. Valence electrons are only available to form the bond with another atom. The formation of the bond can take place either by sharing of valence electrons or by sharing of valence electrons.
