Question

Which is more Stable ( atom or molecule) ?Give reason .

Answer 1

It's the molecule, because during molecule formation, a covalent bond is formed which is responsible for release of energy, hence making the molecule more stable.

Answer 2

A molecule as compared to the atoms from which it is formed is more stable because it possesses energy lower than the energy of the uncombined atoms. This difference in energy is due to the fact that when atoms combine to form molecule, the attractive forces are created which result in release of energy.
