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.

Famous quotes containing the word history:
“The principal office of history I take to be this: to prevent virtuous actions from being forgotten, and that evil words and deeds should fear an infamous reputation with posterity.”
—Tacitus (c. 55–c. 120)
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
“A people without history
Is not redeemed from time, for history is a pattern
Of timeless moments.”
