Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by French chemist Paul-Émile Lecoq de Boisbaudran in 1875, Gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium).. Elemental gallium is a soft, silvery metal in standard temperature and pressure.In its liquid state, it becomes silvery white.

Characteristics: Pure gallium is silvery-white and melts at temperatures under 85°F (29.4°C). The metal remains in a melted state up to nearly 4000°F (2204°C), giving it the largest liquid range of all metal elements. Gallium is one of only a few metals that expands as it cools, increasing in volume by just over 3%.
