gal·li·um

 (găl′ē-əm)
n. Symbol Ga
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, as a component of various low-melting alloys, and in producing blue light-emitting diodes. Atomic number 31; atomic weight 69.72; melting point 29.78°C; boiling point 2,403°C; specific gravity 5.907; valence 2, 3. See Periodic Table.

[From Latin gallus, cock, punning translation of surname of Paul Émile Lecoq de Boisbaudran (1838-1912), French chemist and element's discoverer : French le, the + French coq, rooster.]

gallium

(ˈɡælɪəm)
n
(Elements & Compounds) a silvery metallic element that is liquid for a wide temperature range. It occurs in trace amounts in some ores and is used in high-temperature thermometers and low-melting alloys. Gallium arsenide is a semiconductor. Symbol: Ga; atomic no: 31; atomic wt: 69.723; valency: 2 or 3; relative density: 5.904; melting pt: 29.77°C; boiling pt: 2205°C
[C19: from New Latin, from Latin gallus cock, translation of French coq in the name of its discoverer, Lecoq de Boisbaudran, 19th-century French chemist]

gal•li•um

(ˈgæl i əm)

n.
a rare steel-gray metallic element used in high-temperature thermometers because of its high boiling point (1983°C) and low melting point (30°C). Symbol: Ga; at. wt.: 69.72; at. no.: 31; sp. gr.: 5.91 at 20°C.
[1870–75; < New Latin, derivative of Latin gall(us) cock (translation of French coq, from Lecoq de Boisbaudran, 19th-century French chemist) + New Latin -ium -ium2]
