which of the following ions has the maximum magnetic moment ?

Options

A. `Mn^(+2)`
B. `Fe^(2+)`
C. `Ti^(+2)`
D. `Cr^(+2)`

Answer

A

Explanation

`Mn^(2+) -5` unpaired electrons
`Fe^(2+)-4` unpaired electrons
`Ti^(2+) -2` unpaired electrons
`Cr^(2+) -4` unpaired electrons
Hnece maixumum number of unpaired electron i present in `Mn^(2+)`
Magnetic moment `alpha` number of unpaired electrons
