MCQ
Which is correct about ionisation potential
- AIt is independent of atomic radii
- BIt increases with increase in atomic radii
- CIt remains constant with increase in atomic radii
- ✓It decreases with increase in atomic radii
✓
Answer
Correct option: D.
It decreases with increase in atomic radii
d
(d) 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.
