网页Lithium (from Ancient Greek λίθος (líthos) 'stone'; symbol Li and atomic number 3) is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.
Lithium | Definition, Properties, Use, & Facts | Britannica
网页5 天之前 · Lithium is the only alkali metal that does not form the anion, Li −, in solution or in the solid state. Lithium is chemically active, readily losing one of its three electrons to form compounds containing the Li + cation. Many of these differ markedly in solubility from the corresponding compounds of the other alkali metals.
