Definition of the Gallium Element
A rare metallic element that is liquid near room temperature, expands on solidifying, and is found as a trace element in coal, bauxite, and other minerals. It is used in semiconductor technology and as a component of various low-melting alloys.

Origin / Meaning of the name Gallium
The name originates from the Latin word Gallia meaning France also gallus, meaning "rooster"after himself 'Lecoq' .

Classification of the Gallium Element
Gallium is classified in the 'Other Metals' section which can be located in groups 13, 14, and 15 of the Periodic Table. All of these elements are solid, have a relatively high density and are opaque.

Facts about the Discovery and History of the Gallium Element
Gallium was discovered by Paul Emile Lecoq de Boisbaudran in France in 1875.

Occurrence the Gallium Element
Gallium does not exist in pure form in nature
Found as a trace element in coal, bauxite, and other minerals

Associated Uses of Gallium
Semi-conductors
Component of various low-melting alloys

Gallium and the Periodic Table
Check out Gallium on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Gallium for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Gallium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Gallium is just one element that can be found.
