fluorine (n.)
A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.

fluorine
A gaseous chemical element with symbol F and atomic number 9; a member of the halide family, it is the most electronegative element and the most chemically energetic of the nonmetallic elements; highly toxic and corrosive; used in rocket fuels and as a chemical intermediate.\n(Source: MGH)

Fluorine (symbol F) is a chemical element which exists as a yellow diatomic gas. Its atomic number (which is the number of protons in it) is 9, and its atomic mass is 19. It is part of the Group 7 (halogens) on the periodic table of elements.

It is the most chemically reactive of all the elements.

Chemical properties.

It is very reactive gas, which exists as diatomic molecules. Due to the very high electron affinity of fluorine, the atoms of this element gain electrons very easily.
