Assertion Nitrogen has higher first ionisation energy than oxygen.
Reason Atomic radius of nitrogen is smaller than that of oxygen.

Explain why nitrogen has higher first ionisation enthalpy than oxygen.

Assertion : Nitrogen has higher first ionization energy than that of oxygen. Reason : Nitrogen gas has smaller atomic size than that of oxygen.

Nitrogen has higher ionisation enthalpy than that of Oxygen. Give reaon.

(A) : Nitrogen has higher ionization energy than that of oxygen. (R ) : Nitrogen atom has smaller atomic size than that of oxygen.

Nitrogen has higher ionization enthalpy than that of oxygen.Give reason.

Assertion (A) : The first ionization energy of Al is lower than Mg. Reason (R ) : Atomic radius of Al is smaller than Mg.

Why is the atomic radius of oxygen slightly more than that of nitrogen?

The ionisation energy of nitrogen is more than that of oxygen because

The ionisation energy of nitrogen is more than that of oxygen because
