The melting point of gallium, at 302.9146 K (29.7646 °C, 85.5763 °F), ... Gallium's boiling point, 2673 K, is nearly nine times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, ... Ver mais Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, gallium is in group 13 of the periodic table and is similar to the … Ver mais Gallium is found primarily in the +3 oxidation state. The +1 oxidation state is also found in some compounds, although it is less common … Ver mais In 1871, the existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" from its position in his periodic table. He also predicted several properties of eka-aluminium that correspond closely to the real properties of … Ver mais Gallium is produced exclusively as a by-product during the processing of the ores of other metals. Its main source material is bauxite, the chief ore of aluminium, but minor amounts are … Ver mais Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium is a silvery blue metal that fractures conchoidally like glass. Gallium liquid expands by 3.10% when it solidifies; therefore, it should not be stored in glass or metal containers … Ver mais Gallium does not exist as a free element in the Earth's crust, and the few high-content minerals, such as gallite (CuGaS2), are too rare to serve as … Ver mais Semiconductor applications dominate the commercial demand for gallium, accounting for 98% of the total. The next major application is for gadolinium gallium garnets. Semiconductors Extremely high … Ver mais WebSolution. The correct option is D Gold. Except gold, caesium, gallium and mercury have usually low melting points. Mercury is the only liquid metal with a melting point of −38 ∘C. Cesium is a soft, silvery-gold alkali metal with a melting point of 28 ∘C. Gallium has a melting point of 29.7 ∘C.
