In such a layer, fluorine does not present any absorption bands.
From this it will be understood that the fluorine will be evolved when the stone is fused.
Arsenic combines with fluorine at the ordinary temperature with incandescence.
Their pseudo-flesh is composed mainly of silicon and fluorine.
The preparation of fluorine was finally accomplished by the French chemist Moissan by the electrolysis of hydrofluoric acid.
Iodine, fluorine, &c. had not been discovered at this period.
Oxygen will combine with iron or lead or sodium, but cannot be made to combine with fluorine.
It is ready to unite with every known substance, fluorine excepted.
It is used as the chief source of fluorine compounds, especially hydrofluoric acid.
Had they pumped it full of fluorine, the result would not have been worse.
fluorine fluor·ine (flur'ēn', -ĭn, flôr'-)
A highly corrosive poisonous gaseous halogen element, the most reactive of all the elements. Atomic number 9; atomic weight 18.9984; melting point -219.62°C; boiling point -188.14°C (at 1 atmosphere); specific gravity of liquid 1.108 (at boiling point); valence 1.
A 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. See Periodic Table.
