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.
Answer: Scientists who study evolution may want to know whether two present-day species are closely related. Evidence for evolution can be structural, genetic, or bio geographical. Fossil skeletons of horse relatives dating from various time periods. ... of fossils and living species may tell us how modern organisms evolved. so D
