The atomic radius increases as we move down a group because

A

Effective nuclear charge increases

B

atomic mass increases

C

additive electrons are accommodated in new electron level

D

atomic number increases.

Text Solution

Verified by Experts

The correct Answer is:
C
As we move down a group, additive electrons occupy new energy levels and therefore, atomic radius increases.
