edit. | references. Gallium is a chemical element; it has the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [10] gallium is in group 13 of the periodic table and is similar to the other metals of the group ( aluminium, indium, and thallium ).
Jun 6, 2024 · Gallium, chemical element of Group 13 (the boron group) of the periodic table. It liquefies just above room temperature. Gallium compounds, some of which form the basis for light-emitting diodes (LEDs), have valuable semiconductor and optoelectronic properties.

Jul 26, 2017 · Properties, sources and uses of the element gallium, including gallium scan, gallium arsenide and gallium nitride.
Jan 18, 2019 · Gallium is known for its low melting point, which lends itself to the gallium spoon demonstration and even melting the pure metal in your hand. Here is a collection of gallium facts, including the discovery, properties, uses, and sources of the element.
Gallium is bluish silver metal. It is soft at STP (standard temperature and pressure), while at low temperature, it acquires a brittle solid state. Gallium also exists in liquid form at temperature more than 29.76 °C. When gallium is held in the hand, it melts and is re-solidified when placed back from hand.
Gallium is a liquid at 30°C, so one would expect it to become a solid at 29.7°C. Instead it is fairly easy to cool gallium to below 29.7°C without having it solidify. Gallium's boiling point is about 2,400°C (4,400°F) and its density is 5.9037 grams per cubic centimeter.
gallium, Metallic chemical element, chemical symbol Ga, atomic number 31. Silvery white and soft enough to be cut with a knife, gallium has an unusually low melting point (about 30 °C [86 °F]), which allows it to liquefy in the palm of the hand.
Gallium is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapour pressure even at high temperatures.
Oct 1, 2019 · Properties: Gallium has a melting point of 29.78°C, boiling point of 2403°C, specific gravity of 5.904 (29.6°C), specific gravity of 6.095 (29.8°C, liguid), with a valence of 2 or 3. Gallium has one of the longest liquid temperature ranges of any metal, with a low vapor pressure even at high temperatures. The element has a strong ...
