Question:
The diamagnetic and paramagnetic materials at 300 K are respectively,
The diamagnetic and paramagnetic materials at 300 K are respectively,
Show Hint
Diamagnetism is universal but very weak; paramagnetism requires unpaired electrons.
Updated On: Apr 24, 2026
- Al and Mg
- Cu and Si
- Hg and Ca
- Li and Ag
- Cr and Pb
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Diamagnetic materials are weakly repelled by magnetic fields (e.g., Hg, Cu, Bi). Paramagnetic materials are weakly attracted (e.g., Ca, Al, Pt).
Step 2: Detailed Explanation:
Hg (mercury) is diamagnetic. Ca (calcium) is paramagnetic.
Step 3: Final Answer:
Diamagnetic: Hg, Paramagnetic: Ca.
Diamagnetic materials are weakly repelled by magnetic fields (e.g., Hg, Cu, Bi). Paramagnetic materials are weakly attracted (e.g., Ca, Al, Pt).
Step 2: Detailed Explanation:
Hg (mercury) is diamagnetic. Ca (calcium) is paramagnetic.
Step 3: Final Answer:
Diamagnetic: Hg, Paramagnetic: Ca.
