    Occurrence

    Lithium is found in various natural sources, including minerals, rocks, and the Earth's crust.

    • Not found free in nature due to high reactivity
    • Makes up about 0.002% of Earth's crust
    • Found in minerals like spodumene and lepidolite
    • Present in seawater at very low concentrations
