Fluorine Physical Properties

It is a Pale Yellow Gas, diatomic, highly corrosive, flammable gas, with a pungent odor. Fluorine is Transparent and soft. Its Melting point is -219 degrees celsius, its Boiling point is -188 degrees celsius. Its density is 0.0017 g/cm³. Fluorine is a gas therefore it is not brittle, malleable nor ductile, yet it is elastic. Yes Fluorine is an Isotope, it is anisotope because it has the same atomic number but different atomic mass. Fluorine has 18 isotopes but only one is stable which is fluorine-19.
