Since any orbital can hold a maximum of two electrons, the bonding orbital in H 2 + is only half-full. This single electron is nevertheless enough to lower the potential energy of one mole of hydrogen nuclei pairs by 270 kJ quite enough to make them stick together and behave like a distinct molecular species.
since it has four electrons in its outermost orbital it needs four more electrons to complete its octet since it has two electrons in its outermost orbital it needs four more electrons to complete its octet since it has four electrons its outermost orbital it can donate four electrons to complete its octet
