As we know in beryllium dihydride, the beryllium is taken as a central atom and hydrogen atoms are taken as a side or peripheral atom. In the polyatomic molecules, the orbitals of peripheral atoms combine to form group orbitals. It is the number of electrons each atom in the molecule has gained. The above molecular orbital formation of the beryllium dihydride represents that the two hydrogen atoms combine with the beryllium to form beryllium dihydride.
