Question
Which of the following pairs show reverse properties on moving along a period from left to right and from top to down in a grou
- (a) Nuclear charge and electron affinity
- Ionisation energy and electron affinity
- (c) Atomic radius and electron affinity
- None of these
The correct answer is: (c) Atomic radius and electron affinity
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 severe trends i.e. decrease from top to bottom in a group and increase from left to right in a period.
