(i) as we proceed down the same group in the periodic table and
(ii) as we proceed from left to right in the same period, the atomic radius

A

(i) Increase continuously, (ii) Decreases continuously

B

(i) Decreases continuously, (ii) Increases continuously

C

(i) Increases continuously, (ii) Decreases upto the group IV and then increases upto the end of the period

D

(i) Decreases continuously, (ii) Decreases upto the group IV and then increases upto the end of the period

Text Solution

Verified by Experts

The correct Answer is:
A
From left to right in a period atomic radius decreases generally while in the group from top to bottom atomic radius increases.
