Ga is a chemical element with the symbol Ga and atomic number 31. It is a soft, silvery metal that is part of the group 13 elements in the periodic table. Gallium is known for its low melting point, which allows it to melt in your hand. It is primarily used in electronics, particularly in the production of semiconductors and LEDs. Gallium does not occur in nature as a free element but is found in trace amounts in bauxite and zinc ores. It is often used in alloys to lower melting points and in various applications, including solar panels and high-temperature thermometers.
