Question

What is the magnetic moment of nickel ion in tetraammine nickel(ii) chloride?

Answer 1

Answer:

3.46 BM

Explanation:

Ni(2+) is d8 system. When it forms a tetrahedral complex it will have 3 unpaired electron.

We know the formula for magnetic moment

μ=$\sqrt{n(n+2)}$

where n is no of unpaired electron

putting value of unpaired electron

μ=$\sqrt{3(3+2)}$ = 3.46 BM
