Lítíọ̀mù

(Àtúnjúwe láti Lithium)

Lítíọ̀mù (play /ˈlɪθiəmu/, LI-thee-əm) ni metali múlọ́múlọ́ fàdákà-funfun to wa ni ẹgbẹ́ mẹ́tàlì álkálì ti awon ẹ́límẹ̀ntì kẹ́míkà. Àmì-ìdámọ̀ rẹ̀ ni Li, tó sì ní nọ́mbà átọ̀mù 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.

6Li content may be as low as 3.75% in
natural samples. 7Li would therefore
have a content of up to 96.25%.
