Assertion:On moving down the group the group,ionization enthalpy decreases.
Reason:With decreases in size of the atom,the force of attraction between the nucleus and valence electrons decreases.

A

If both assertion and reason is the correct explanation of assertion.

B

If both assertion and reason is the correct explanation of assertion.

C

If both assertion and reason is the correct explanation of assertion.

D

If both assertion and reason is the correct explanation of assertion.

Text Solution

Verified by Experts

The correct Answer is:
C
I.E decreases down the group due to increase in atomic size and the outermost electeronbeing increasingly father from the nucleus,there is an inreased shielding of the nuclear charge by the electrons in the inner levels.
