The maximum and minimum melting points of first and second transition series respectively are observed with

A

Cr and Zn

B

Cr and Hg

C

V and Cd

D

Cr and Cd

Text Solution

Verified by Experts

The correct Answer is:
D
Melting point is maximum for `cr` (`ns^(1)` and `(n-1)d^(5)e^(-)` both are involved in bonding) due to completely filled nature `(ns^(2)(n-1)d^(10))` cd possess low m.p
