Which of the following pairs show reverse properties on moving along a period from left to right and from top to down in a group?

A

Nuclear charge and electron affinity

B

Ionisation energy and electron affinity

C

Atomic radius and electron affinity

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Atomic radius increase from top to bottom in a group while decrease from left to right in a period. On the other hand electron affinity shows reverse trends i.e. decrease from top to bottom in a group and increase from left to right in a period.
