Question

Magnetic moment 2.83 BM is given by which of the following ions ?
(At. nos. Ti = 22, Cr = 24, Mn = 25, Ni = 28):-
(a) Ti³⁺
(b) Ni²⁺
(c) Cr³⁺
(d) Mn²⁺

Answer 1

Ni+2

t2g6 and eg2

Root 8 = 2.83 B.M

Answer 2

Answer:

Ni+2

Explanation:

Magnetic moment is given by u = root n(n+2) BM..

n = no. of unpaired electron..

Here 2.83 = n = 2..

Ni+2 has two unpaired electron ..

So, the answer is 2nd..

Hope it helps!!!!
