    Occurrence

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

    • 42nd most abundant element in Earth's crust (0.00011%)
    • Never found as native metal in nature
    • Primary ore is molybdenite (MoS₂)
    • Often obtained as a byproduct of copper mining
    • Present in soil, plants, animals, and some deep ocean waters
