The loss of an electron from a diatomic molecule results in decrease on its bond
energy explain with example.

Key Points
The Aufbau principle states that orbitals are filled with the lowest energy first.
The Pauli exclusion principle states that the maximum number of electrons occupying an orbital is two, with opposite spins.
Hund’s rule states that when there are several MOs with equal energy, the electrons occupy the MOs one at a time before two occupy the same MO.
Key Terms
antibonding: an atomic or molecular orbital whose energy increases as its constituent atoms move closer together, generating a repulsive force that hinders bonding
antibonding orbital: one that is located outside the region of two distinct nuclei

Explanation:
A diatomic molecule is a molecule having only two atoms, either from the same element or different elements. Since in normal state, the valence bond is stable for a diatomic molecule, so it does not break its bond but when we change its valance configuration by taking out an electron, it gets unstable and it is easier to break its bond then
