Question

Explain the following giving reasons: noble gases have very high value of I.P?​

Answer 1

Answer:

Ionization energy of noble gases is very high in comparison to other elements of the same period. This is due to extra stability on attaining the compete octet in out a shell.

Explanation:

I hope it helps you.

Answer 2

Answer:

The very high value of the ionisation enthalpies of noble gases are due to their high values of effective nuclear charge and stable electronic configuration (ns2 np6) i.e. fully filled s and p-orbitals).

Inert gases have very high ionization potential because of it having fully filled orbitals which are a cause of their stability. As they have full filled orbitals they have perfect symmetry and a larger value of exchange energy which causes the atom to have lesser internal energy and hence, it becomes stable.
