Gallium (Gallium) is a grayish-blue or silvery-white metal with the element symbol Ga and an atomic weight of 69.723.Gallium has a very low melting point but a high boiling point. Pure liquid gallium has a remarkable tendency to supercool and oxidizes readily in air, forming an oxide film. Gallium was the first element predicted and confirmed in nature according to the periodic law of the chemical elements, and is the liquid substance with the greatest electrical and thermal conductivity at room temperature.
