Question
Which is correct about ionisation potential
- (a) It is independent of atomic radii
- It increases with increase in atomic radii
- (c) It remains constant with increase in atomic radii
- It decreases with increase in atomic radii
The correct answer is: It decreases with increase in atomic radii
We know that ionisation potential gradually decreases of moving down the group while atomic size increases as we move down the group. Hence larger the atomic size, smaller is ionisation potential.
