How is bonding molecular orbital of hydrogen different from the antibonding molecular orbital ?

According to molecular orbital theory molecules are said to be stable if the number of electrons in bonding molecular orbitals is …………… the number of electrons in antibonding molecular orbitals.

Molecular orbitals are formed by the overlap of atomic orbitals. The combining orbitals must have proper orientation so that they can overlap to a considerable extent. Two atomic orbitals combine to form two molecular orbitals called bonding molecular orbital and antibonding molecular orbital. Bonding molecular orbital is stable and antibonding molecular orbital is unstable. sigma MO is formed by head on overlap while pi MO is formed by sidewise overlap. The MOs are filled with electrons according to the same rules as followed for filling atomic orbitats. Bond order is one of the most important parameter to compare the bond strength and bond length of bonds. Why has N_2 a larger dissociation energy than N_2 ^(+) whereas O_2 has a lower dissociation energy than O_(2)^(+) ?

If E is the total energy of the combining atomic orbitals, and E_b and E_a are the energies of the bonding and antibonding molecular orbitals formed, respectively, then

According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbital formed. Number of atomic orbitals overlapping together is equal to the molecule orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbitals by an amount Delta . This known as the stabilization energy. The enerby of antibonding molecular orbital in increased by Delta' (destabilisation energy). Q. Which of the following statements is not correct regarding bonding molecular orbitals?
