aluminum[ə lo̵̅o̅′mə nəm]
a silvery, lightweight, easily worked, metallic chemical element that resists corrosion and is found abundantly, but only in combination: symbol, Al; at. no., 13
Origin of aluminumModern Latin ; from Classical Latin alumen: see alumina
of, containing, or made of aluminum
A silvery-white, ductile metallic element, the most abundant in the earth's crust but found only in combination, chiefly in bauxite. Having good conductive and thermal properties, it is used to form many hard, light, corrosion-resistant alloys. Atomic number 13; atomic weight 26.9815; melting point 660.32°C; boiling point 2,519°C; specific gravity 2.70; valence 3. See Periodic Table.
Origin of aluminumalumin(a) + –(i)um.
Named in 1812 by British chemist Sir Humphry Davy who discovered it, after the earlier 1807 New Latin form alumium.
