Calculate the number of unpaired electrons in the following gaseous ions: Mn 3+ , Cr 3+ , V 3+, and Ti 3+ . Which one of these is the most stable in aqueous solution?

Question

Philoid · Accepted Answer

From the table given below:

Mn³⁺ : 3d⁴	unpaired electrons = 4
V³⁺ : 3d²	unpaired electrons =2
Cr³⁺ : 3d³	unpaired electrons= 3
Ti³⁺ : 3d¹	unpaired electrons =1

Cr³⁺ is most stable in aqueous solution because of half filled d-orbital.
