The most reactive chemical element, F(2), has been claimed not to occur in nature. First direct evidence from in situ NMR spectroscopy now proves that elemental F(2) indeed occurs in nature as an occlusion in "antozonite" (right in the picture), a variant of fluorite (CaF(2), left).
有报道称，自然界中不存在最活泼的化学元素 F(2)。现在，原位核磁共振波谱学的直接证据首次证明，元素 F(2)实际上以包裹体的形式存在于“氟碳铈矿”（右图）中，这是萤石（CaF(2)，左图）的一种变体。
