MCQ
On moving down a group of regular elements, both atomic and ionic radii increases with increasing
- ✓Atomic number
- BAtomic weight
- CAtomic mass
- DNone of these
✓
Answer
Correct option: A.
Atomic number
a
On moving down the group, as atomic no. increases, atomic radii and ionic radii increases. As $e { }^{-}$s are added to new orbitals thereby increasing the radii.
