GENERAL KNOWLEDGE

Detailed explanation-1: -Valence electrons are the electrons located at the outermost shell of an atom. … Because when two atoms interact, the electrons in the outermost shells are the first ones to come into contact with each other and are the ones that determine how an atom will react in a chemical reaction.

Detailed explanation-2: -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-3: -The atomic number defines an element’s chemical properties. The number of electrons in an atom determines bonding and other chemical properties. In a neutral atom, the atomic number, Z, is also the number of electrons.
