Fzone

Fzone, also known as flozone or trifluorine, is an artificial allotrope of fluorine consisting of three fluorine atoms covalently bonded to each other (sigma-bonds, F3). Although incredibly unstable and almost impossible to make under normal conditions, it is possible to stabilise fluorine using nectism. Fluorine is an analogue to ozone and clozone.

Chemical properties
Fzone is incredibly electronegative.
