we know that the formula for magnatic moment=
where n is no. of unbonded electrons.
as the ion has a charge of +a then a=no.of unbonded electrons.
squaring both sides
a(a+2)=24
a2+2a-24=0
a2+6a-4a-24=0
a(a+6)-4(a+6)
we conclude that a has 2 values -6 and + 4
since M has a positive charge we may have the result as a =4
