Gallium is a chemical element with the symbol Ga and the atomic number is 31. Gallium is a rare soft silver true metal. At low temperatures it is brittle but at above room temperature it is a liquid. Paul-Emile Lecoq de Boisbaudran in 1875 in France.
Gallium is never found as free form in nature. It is found and extracted as a trace component in these compunds (Baucite, Coal, Diaspore, Germanite, and Sphalerite.) [1]
As a solid, gallium is seen as a blue gray metal with orthorhombic crystalline structure. Gallium is only a silver color when it is in its purest form. gallium takes the solid form at room teperature, butwiththe slightest heat added it chages to a liqued form along with mercury, cesium, and rubidium. when a solid gallium can be cut with a nife, it reacts with and disolves in acids and alkalis. [2]
Uses
Gallium is used to wet glass or porcelain to form a brilliant moirror when painted on glass.
