easy

If ${N_x}$ is the number of bonding orbitals of an atom and ${N_y}$ is the number of antibonding orbitals, then the molecule/atom will be stable if

${N_x} > {N_y}$

${N_x} = {N_y}$

${N_x} < {N_y}$

${N_x} \le {N_y}$

Solution

Bonding and antibonding orbitals

It is combined the atomic orbitals where the molecular orbitals are formed. The antibonding orbitals has more energy than bonding orbitals. The electrons which present into the nuclei of $2$ atoms placed in the bonding orbitals for maximum time. It is more stable due to lower energy. The electrons which present into the nuclei of $2$ atoms outside the bonding orbitals for maximum time. It is less stable due to higher energy.
