Question

Calculate the magnetic moment of sc+2

Answer 1

Electronic configuration of Sc = 1s²2s²2p⁶3s²3p⁶3d¹4s²

Electronic configuration of Sc⁺² = 1s²2s²2p⁶3s²3p⁶3d¹

\(\therefore\) Magnetic moment = \(\sqrt{n(n+2)}\) B.M.

Where,

n = Number of unpaired elecrons.

\(\therefore\) Magnetic momental Sc⁺² = \(\sqrt{1(1+2)}\) B. M.

= √3 B.M.

= 1.732 B.M.
