title: Lithium text: Lithium Lithium (from ) is a chemical element with symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals which were once the main source of lithium. Due to its solubility title: Lithium text: Lithium aluminium hydride () is commonly used as a reducing agent in organic synthesis. Multiple organolithium reagents are known in which there is a direct bond between carbon and lithium atoms, effectively creating a carbanion. These are extremely powerful bases and nucleophiles. In many of these organolithium compounds, the lithium ions tend to aggregate into high-symmetry clusters by themselves, which is relatively common for alkali cations. LiHe, a very weakly interacting van der Waals compound, has been detected at very low temperatures. Naturally occurring lithium is composed of two stable isotopes, Li and Li, the latter being the more abundant title: Lithium fluoride text: Lithium fluoride Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid, that transitions to white with decreasing crystal size. Although odorless, lithium fluoride has a bitter-saline taste. Its structure is analogous to that of sodium chloride, but it is much less soluble in water. It is mainly used as a component of molten salts. Formation of LiF from the elements releases one of the highest energy per mass of reactants, second only to that of BeO. LiF is prepared from lithium hydroxide or lithium carbonate with hydrogen fluoride. Fluorine is produced by the title: Lithium nitride text: Lithium nitride Lithium nitride is a compound with the formula LiN. It is the only stable alkali metal nitride. The solid is a red or purple color and has a high melting point. Lithium nitride is prepared by direct combination of elemental lithium with nitrogen gas: Instead of burning lithium metal in an atmosphere of nitrogen, a solution of lithium in liquid sodium metal can be treated with N. Lithium nitride reacts violently with water to produce ammonia: "alpha"-LiN (stable at room temperature and pressure) has an unusual crystal structure that consists of two types of layers, one sheet has title: Lithium carbide text: Lithium carbide Lithium carbide, , often known as dilithium acetylide, is a chemical compound of lithium and carbon, an acetylide. It is an intermediate compound produced during radiocarbon dating procedures. is one of an extensive range of lithium-carbon compounds which include the lithium-rich , , , , , , and the graphite intercalation compounds , , and . is the most thermodynamically-stable lithium-rich compound and the only one that can be obtained directly from the elements. It was first produced by Moissan, in 1896 who reacted coal with lithium carbonate. <chem>Li2CO3 + 4C->Li2C2 + 3CO </chem> The other lithium-rich compounds
