Detailed explanation-1: -In chemical bonding, only the valence electrons i.e., the electrons located in the orbitals of the outermost energy level (valence shell ) of an element is involved.
Detailed explanation-2: -In general, electrons are involved in chemical bonding through the formation of ionic, covalent, or metallic bonds. In ionic bonding, outer electrons are transferred from one substance to another, forming oppositely charged ions. In covalent bonding, outer electrons are shared between atoms of a molecule.
Detailed explanation-3: -A stable arrangement is attended when the atom is surrounded by eight electrons. This octet can be made up by own electrons and some electrons which are shared. Thus, an atom continues to form bonds until an octet of electrons is made.
