History
Gallium (Ga) was discovered in 1875 by P.É. Lecoq de Boisbaudran. In most of its compounds, Gallium is found with an oxidation number of 3+. Gallium chemically behaves as close as Iron 3+ when contacting in a complex. That means, Gallium (III) and Iron (III) have similar coordination numbers, electrical charge, ion diameter and electron configuration.
