उत्तर

While going from top to bottom in a group the atomic radius increases.

Explanation:

When moving from top to bottom in a group, the atomic radius increases. This occurs because each subsequent element down the group has an additional electron shell, which increases the distance between the nucleus and the outermost electrons.
