The atomic radius of elements of which of the following series would be nearly the same

A

Na , K , Rb, Cs

B

Li , Be , B, C

C

Fe , Co , Ni, Cu

D

F , Cl , Br , I

Text Solution

Verified by Experts

The correct Answer is:
C
`Fe,Co, Ni,Cu`. Due to shielding of d-electrons, the effect of increased nuclear charge due to increase in atomic no. neutralised. Consequently atomic radius remains almost unchanged after chromium.
