प्रश्न
Explain the octet rule for the formation of –
Nitrogen molecule from two nitrogen atoms.
Advertisements
उत्तर
Each atom of nitrogen has 5 electrons in outermost orbit. For both, it is not possible to gain 3 electrons or lose 5 electrons to attain the nearest inert gas electronic configuration. So they share 3 electrons each and attain octet configuration which is stable and form N2 molecule.
