Fluorine is a Group VII element. Fluorine forms compounds with metals and non-metals.
Tetrafluoroethene is an unsaturated compound with the formula C2 F4. Tetrafluoroethene is the monomer used to make the polymer poly(tetrafluoroethene).
Tetrafluoroethene can be polymerised to form poly(tetrafluoroethene).
Draw one repeat unit of poly(tetrafluoroethene). Show all of the atoms and all of the bonds.
