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.neutraslised. Consequently atomic radius remain almost unchanged after chromium.
