L.C.A.O. principle is involved in the formation of molecular orbitals according to molecular obtital theory. The energy of bonding molecular orbital is less than that of the combining atomic orbitals while that of the anitibonding bonding melecular orbital is more. The B.O. `=^(1//2)[N_(b)-N_(a)]`
Answer the following questions on the basis of the above paragraph :
(i) What is bonding molecular orbital ?
(ii) Calculate B.O. of `He_(2)` molecule.
