Metallic radii of some transition elemen...

Metallic radii of some transition elements are given below.

Which of these elements will have highest density ?

A

Fe

B

Ni

C

Co

D

Cu

Text Solution

Verified by Experts

The correct Answer is:
D
On moving left to right along period, metallic radius decreases while mass increases. Decreases in metallic radius coupled with increase in atomic mass results in increase in density of metal.
Hence, among the given four choices Cu belongs to right side of Periodic Table in transition metal, and it has highest density `(89g//cm^3)`.
