Metal Oxides: Chemistry and Appliions - CRC Press … The chemistry of metals has traditionally been more understood than that of its oxides. As alytic appliions continue to grow in a variety of disciplines, Metal Oxides: Chemistry and Appliions offers a timely account of transition-metal oxides (TMO), one of the most important classes of metal oxides, in the context of alysis.

Paramagnetism of Transition Metal Salts | Chemdemos

Paramagnetism is when a substance is weakly attracted to a magnetic field. It occurs when there are unpaired electrons in the substance. Paramagnetism is most easily observed in the salts of some of the first row transition metals (manganese through nickel). The se metal ions have unpaired electrons in degenerate d orbitals as predicted by Hund''s rule and thus exhibit paramagnetism.
