WebJan 4, 2024 · The main group elements (also known as the representative elements) in the periodic table are the chemical elements of s-block and p-block (except hydrogen ). … WebThe elements present in s- and p-blocks except inert gases are collectively known as representative elements or main group elements. These elements have filled inner orbitals and unfinished outermost orbitals, valence shells. The representative elements or main group elements include all nonmetals and a few metals.
