Lithium (from Ancient Greek: λίθος, líthos, 'stone') is a chemical element; it has symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as ...
Lithium is used to treat the manic episodes of manic depression - hyperactivity, rushed speech, poor judgment and aggression. Learn about side effects, interactions and indications.
Description Lithium is used to treat mania that is part of bipolar disorder (manic-depressive illness). It is also used on a daily basis to reduce the frequency and severity of manic episodes. Manic-depressive patients experience severe mood changes, ranging from an excited or manic state (eg, unusual anger or irritability or a false sense of well-being) to depression or sadness. It is not ...
Lithium, chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale. Learn more about the occurrence and uses of lithium.
