Question:
Which from following is a soft metal?
Which from following is a soft metal?
Show Hint
Most d-block metals are hard, but metals with completely filled d orbitals such as zinc group metals are soft.
Updated On: Nov 13, 2026
- Cr
- V
- Co
- Cd
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Hardness in transition metals depends on the number of unpaired d electrons available for metallic bonding.
Step 2: Compare
Cr, V and Co have many unpaired d electrons, so they are hard. Cd has the configuration \(4d^{10}5s^2\) with no unpaired d electrons.
Step 3: Result
Cd has weak metallic bonding and is a soft metal.
Final Answer:
Cd is the soft metal. \[ \boxed{\text{(D) }\text{Cd}} \]
