The real element would corrode even borosilicate glass.
: flow or flux Properties: Fluorine has a melting point of -219.62°C (1 atm), boiling point of -188.14°C (1 atm), density of 1.696 g/l (0°C, 1 atm), specific gravity of liquid of 1.108 at its boiling point, and valence of 1. It is highly reactive, participating in reactions with virtually all organic and inorganic substances. Metals, glass, ceramics, carbon, and water will burn with a bright flame in fluorine.
Free fluorine has a characteristic pungent odor, detectable at concentrations as low as 20 ppb.
Both elemental fluorine and the fluoride ion are highly toxic.
The recommended maximum allowable concentration for a daily 8-hour time-weighted exposure is 0.1 ppm.
a toxic pungent pale yellow gas of the halogen group that is the most electronegative and reactive of all the elements, occurring principally in fluorspar and cryolite: used in the production of uranium, fluorocarbons, and other chemicals.

(flr'ēn') Symbol FA pale-yellow, poisonous, gaseous element of the halogen group.
It is highly corrosive and is used to separate certain isotopes of uranium and to make refrigerants and high-temperature plastics.
It is also added in fluoride form to the water supply to prevent tooth decay.
Atomic number 9; atomic weight 18.9984; melting point -223°C; boiling point -188.14°C; specific gravity of liquid 1.108 (at boiling point); valence 1.
This a simulant, showing how fluorine appears (though the actual gas would be less intensely colored in small volumes).Tags: Adult Dating, affair dating, sex dating
