Helium (He) is an element in group 8A of the periodic table, which is a group of element referred to as NOBLE GASES. Other elements in this group are Xenon (Xe), Krypton (Kr), Neon (Ne) etc.
One major characteristics of Helium and other Noble gases that makes them so UNREACTIVE is that they have a full electronic configuration i.e. they have a full electron shell and do not share electrons with any element, which is the basis of REACTING. For this reason, Helium will not react with any element.
