Lithium (
/ˈlɪθiəm/, LI-thee-əm) je is a soft, silver-white ide mulomulo fadaka-funfun to wa ni adipo ide alkali ti awon apilese kemika. O je sisoju pelu ami-idamo Li, beeni o si ni nomba atomu 3. Labe awon ipo opagun o je ide tofuyejulo ati apilese alaralile kiki die julo. Bi gbogbo awon ide alkali, lithium je adarapomora gidigidi, o si le gbana. Nitori idi eyi, inu epo alumoni lo ma unje fifipamosi. Nigba toba je gige, lithium ri bi luster onide, sugbon ti afefe tutu ba fe si oju re yio je kiakia to a dull silvery gray, then black, tarnish. Because of its high reactivity, lithium never occurs free in nature, and instead, only appears in compounds, usually ionic ones. Lithium occurs in a number of pegmatitic minerals, but is also commonly obtained from brines and clays. On a commercial scale, lithium is isolated electrolytically from a mixture of lithium chloride and potassium chloride.
