Q. Which is correct about ionisation potential?
A) It is independent of atomic radii
B) It increases with increase in atomic radii
C) It remains constant with increase in atomic radii
D) It decreases with increase in atomic radii
Explanation
(d)
We know that ionisation potential gradually decreases on moving down the group while atomic size increases as we move down the group. Hence, larger the atomic size, smaller is ionisation potential.
