Question

The value of the magnetic moment of a
particular ion is 2.83 Bohr Magneton. The ion
is-​

Answer 1

Answer:

Ni+2 is right option

bohr magneton =√n(n+2) here n is no. of unpaired electron ,, Ni electronic configuration is 4s2,3d8 and for Ni+2, 2 electron is remove from 4s orbital in 3d8 ; 2 electron is unpaired ..... bohr magneton=√2(2+2) , bohr magneton= √8 ,, bohr magneton is 2.828
