Difference between Fluorine and Atomic Number 9

FLUORINE vs ATOMIC NUMBER 9: NOUN

A fluorine atom.
The chemical element (symbol F) with an atomic number of 9.
A non-metallic, gaseous element of atomic number 9, strongly acid or negative, and 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, but may be contained in lead vessels. If set free it immediately attacks a containing glass vessel, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.00.
A pale-yellow, highly corrosive, poisonous, gaseous halogen element, the most electronegative and most reactive of all the elements, existing as a diatomic gas (F2) and used in a wide variety of industrially important compounds. Atomic number 9; atomic weight 18.9984; melting point −219.67°C; boiling point −188.12°C; specific gravity of liquid 1.50 (at boiling point); valence 1. : Periodic Table.
A nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite

DNA Holliday junction stabilized by fluorine halogen bond.
Studies relating to the toxicity of fluorine compounds.
Of all the elements, fluorine is the most electronegative, so the bonding electrons are being held tightly to the fluorine atoms.
In other embodiments, separated fluorine is passed, either alone or in conjunction with additional feed stock comprising fluorine, to a plasma generator.
Skeletal and soft tissue fluorine deposition and fluorine toxicosis.
With plants that are sensitive for fluorine exposure even low concentrations of fluorine can cause leave damage and a decline in growth.
Comparing fluorine and chlorine is not ideal, because fluorine breaks the trend in the group.
In Kenya fluorine deficiencies are not common, but drinking water especially from boreholes often contain very high levels of fluorine.
Just adding fluorine to water will produce flames as the fluorine turns into a gas.
