Answer to Question #281705 in General Chemistry for Chuchutvvvvvv

Question

Considering you do not focus on the electron configuration to determine the magnetic property of atom, instead, you are to determine it experimentally. How does a diamagnetic substance react to a magnetic field? How will a molecule react if it contains more unpaired electrons? *

Answer 1

In diamagnetism, another magnetic phenomenon, electrons within a substance respond to the outside magnetic field by, essentially, spinning faster. All this spinning generates magnetic forces that resist the outside field. Because all atoms possess electrons, all materials are diamagnetic to some degree.

More unpaired electrons increase the paramagnetic effects. The electron configuration of a transition metal (d-block) changes in a coordination compound; this is due to the repulsive forces between electrons in the ligands and electrons in the compound.
