Why atomic size increases on going down ...

Why atomic size increases on going down the group? Arrange the following in decreasing order of their atomic size -Na, Li, Rb, Cs, K.

Text Solution

Verified by Experts

This is because, on going down a group, new shells are added. This increases the distance between the outermost electrons and the nucleus. `Cs gt Rb gt K gt Na gt Li`
