Question

Calculate the spin magnetic moment of m2+ion(z=27)

Answer 1

Answer:

3.8 BM is the right answer.

Explanation:

The electronic configuration for M with atomic number 27 is [Ar] 3d7 4s2.

For M2+ excited state - [Ar] 3d7 4s0

D - block has 7 electrons, out of which 3 unpaired.

Hence spin magnetic moment is (Refer attachment for calculation)
