☺☺☺Ur answer☺☺☺Hi,The spin MAGNETIC MOMENT is calculated by given below formula :where n is number of unpaired ELECTRON.Electronic configuration of SCANDIUM : [Ar] 3d1 4s2Electronic configuration of Sc+3 : [Ar] 3d0 4s0So, number of unpaired electron in Sc+3 is zero.The spin only magnetic moment of Sc+3 is zero.hope help u...✔✔✔✔✔
