A trend which is common to elements of both the group 1 st and group 17 th , on going from top to bottom

Options

  1. ABoiling point increases
  2. BElectorn affinity increases
  3. COxidising power increases
  4. DIonization energy decreses.

Correct answer

D. Ionization energy decreses.

Step-by-step solution

A trend which is common to elements of both the group 1 st and group 17 th , on going from top to bottom is that the ionization energy decreases since the atomic size increases.
