QJEEM22Ch1a28: JEE Main 2022 Chemistry - Class 12 JEEM22Ch1a28 Solution: The metal ion (in gaseous state) with lowest spin-only magnetic …
The metal ion (in gaseous state) with lowest spin-only magnetic moment value is :
Multiple Choice Options
- A V2+
- B Ni2+
- C Cr2+
- D Fe2+
Step-by-Step Verified Solution
| Valence shell configuration | Unpaired electrons | |
|---|---|---|
| V2+ | 3d34s0 | n = 3 |
| Ni2+ | 3d84s0 | n = 2 |
| Cr2+ | 3d44s0 | n = 4 |
| Fe2+ | 3d64s0 | n = 4 |
Since Ni2+ has least number of unpaired electrons. Hence Ni2+ will have lowest spin only magnetic moment Value.
