First Fluorine Gas Found In Nature
Fluorine gas (F2), which has been called chemistry’s hellcat, is so reactive that chemists have long assumed it does not occur in nature. Now researchers in Munich have evidence that the gas exists naturally, trapped inside a dark purple fluorite mineral called antozonite (Angew. Chem. Int. Ed., DOI: 10.1002/anie.201203515).
