Statement 1: The spin only magnetic moment of Sc3+ is 1.73 B.M.Statement 2: The spin only magnetic moment of an ion is equal to nn+2; where n is the number of unpaired electrons in the ion.

Statement 1: False; Sc3+ ion has no unpaired electron 3d04s0 and thus has zero magnetic moment.Statement 2: Magnetic moment is due to 'spin only' = nn+2 B.M. value. n is number of unpaired electron(s).
