Fluoride can be defined as organic and inorganic compounds consisting of fluorine element. A fluoride ion is fluorine in its ionic form. Fluoride can form a binary compound with another element. There are a number of common fluoride components including sodium fluoride, calcium fluoride, oxygen difluoride and hydrofluoric acid.
Fluoride is prescribed as a medication in its concentrated form. Fluoride is also believed to strengthen the enamel of tooth. The common uses of fluoride include adding its components to toothpaste for preventing cavities, prescribed for treatment, purification of drinking water, and uses as a component in other oral hygiene products
Liquid coolant
Fluorine forms a very large range of compounds since it is highly reactive (actually it is the most reactive element there is). Teflon and freon are both synthetic fluorine compounds. Fluorine salts such as potassium fluoride are used in toothpaste, or to fluoridate water.
Fluorine seems a likely answer
Fluorine.
As fluoride it's used to prevent tooth decay, in toothpastes and in water supplies.
Fluorine
Scientists have known about Fluorine for longer than it has been being used. Fluorine has been around since the 1800s. It is currently being used in toothpaste, refrigerators and rocket fuel.
Freon is a gas used in refrigerators while Teflon is a nonstick substance used in pans.
Refrigerators are used in houses
Neon gas is used in refrigerators.
Chlorofluorocarbons are compounds made of carbon, chlorine, fluorine, and hydrogen. They are bad for the environment and come from aerosol sprays and refrigerators.
Helium can be used in refrigerators, but this application is expensive, not commercial.
CFCs (chlorofluorocarbons) are a type of synthetic compounds that were commonly used as refrigerants, solvents, and propellants in aerosol sprays. However, their use has been largely phased out due to their harmful impact on the ozone layer, which led to the development of more environmentally friendly alternatives.
refrigerators
Fluorine is used to prepare UF4, UF6, UO2F2.
CFC's are used in refrigerators. They are extremely harmful for ozone layer.
