Which of the following species is diamagnetic? View Available Hint (s) Hint 1. How to determine magnetism Which of the following species is diamagnetic? Cl Al Fe2 + S2-

Cl = 1s2 2s2 2p6 3s2 3p5

Al = 1s2 2s2 2p6 3s2 3p1

Fe2 + = 1s2 2s2 2p6 3s2 3p6 4s2 3d4

S2 - = 1s2 2s2 2p6 3s2 3p6

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. If all electrons in the particle are paired, then the substance made of this particle is diamagnetic.

S2 - is diamagnetic because of its paired electrons in the outermost shell.
