Correct order of atomic Radii (Metallic radii)

A
$Mn\, >\, Cr$
B
$Cu\, <\, Zn$
✓
Both $(A)$ and $(B)$
D
$Cr\, >\, Mn$

✓

Answer

Correct option: C.

Both $(A)$ and $(B)$

c
The value is second IE generally increases towards the right in period, however $Cr ^{+}$has $3 d^5$ configuration which is extra-stable. Hence $2^{\text {nd }} IE$ of $Cr$ is more than that of Mn. Thus correct order of $2^{\text {nd }}$ IE is $C r>M n>V>T i$
