Answer:
Explanation:
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.
