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.

The Reaction Of Magnesium With Oxygen | Reactions Of …

When iron is exposed to oxygen in the air, a similar reaction occurs, but much more slowly. The iron is gradually ''eaten away'' as it reacts slowly with the oxygen. Under wet conditions iron will rust more quickly. Rust is actually a mixture of different oxides of 2 O

Similarities Between Magnesium, Calcium, Potassium & …

Both sodium and potassium are in the first vertical column of the periodic charge, making them Group 1 alkali metals. Alkali metals are extremely reactive. For example, dropping even a small amount of pure sodium metal in room temperature water creates an intensely strong reaction that produces high temperatures and generates hydrogen gas.
