In halogens, with increase of atomic number where habit is found

A

Ionisation potential decrease

B

Ionic radii potential decreases

C

Habit to loose electron decreases

D

In `MX_(2)` (`M`= metal `X` = halogen), covalent properties decrease.

Text Solution

Verified by Experts

The correct Answer is:
A
Ionisation potential decreas. Since, atomic size increases.
