QAIPMT-2010-Ch-2024: NEET 2010 Chemistry - Class 12 AIPMT-2010-Ch-2024 Solution: AB crystallizes in a body centered cubic lattice with edge…
AB crystallizes in a body centered cubic lattice with edge length 'a' equal to 387 pm. The distance between two oppositely charged ions in the lattice is 335 pm 250 pm 200 pm 300 pm
Multiple Choice Options
- A Ni 3+
- B Mn 3+
- C Fe 3+
- D Co 3+
Step-by-Step Verified Solution
The electronic configuration of the given
ions is :
Ni 3+ : [Ar]3d 7 4s 0
Mn 3+ : [Ar]3d 4 4s 0
Fe 3+ : [Ar]3d 5 4s 0
Co 3+ : [Ar]3d 6 4s 0
Thus, Co 3+ is the ion with the desired configuration.
