Question

The spin only magnetic moment of Sc3+ is zero why​

Answer 1

Answer:

unpaired electron,

Explanation:

The spin magnetic moment is calculated by given below formula :=rout under n{n+1}

where n is number of unpaired electron.

Electronic configuration of Scandium : [Ar] 3d​1 4s2

Electronic configuration of Sc+3 : ​[Ar] 3d​0 4s0

So, number of unpaired electron in Sc+3 is zero.

The spin only  magnetic moment of Sc+3 is zero.

i hope u understand
