Lanthanum La
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.
Lithium is a metal element, known as the green energy metal and "white oil", widely used in energy storage, chemical industry, medicine, metallurgy, electronics industry and other fields. Lithium is located in the second cycle of the periodic table of the elements IA, element symbol Li. Its atomic number is 3, atomic weight 6.941, melting point is 180.5 ℃, boiling point of 1342 ℃, specific heat capacity of 3.58 kJ/kg-K, corresponding to the monomers for the silver-white soft metal, in all known metals in the lightest specific gravity. It can react with water, soluble in nitric acid, liquid ammonia and other solutions.
