AIEEE 2011 Chemistry - Coordination Compounds Question 264 English Explanation

i.e. the number of unpaired electrons in [NiCl4]2−  {\left[ {NiCl{}_4} \right]^{2 - }}\,\, is 2.2.

n=n(n+2)=2(4)n = \sqrt {n\left( {n + 2} \right)} = \sqrt {2\left( 4 \right)}

=22=2×1.41= 2\sqrt 2 = 2 \times 1.41

=2.82 BM= 2.82\,BM
