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.
Toothpaste is a very common use.
Chlorine and Bromine are used are Purifying agents in Pools/Spas. Fluorine in compounds (Fluoride) is used in Dentistry. Iodine is used as an antiseptic, and has dietary benefits for the Thyroid. Astatine is radioactive and has uses in Nuclear Medicine.
There are two gases in fluorine(Halogen) family, which are Fluorine and Chlorine. In some cases bromine can also be included as a gas.
Halogens have various practical uses, such as disinfectants (chlorine), in producing plastics (fluorine), in photography (bromine), and in water purification (iodine). They are also used in manufacturing medicines and chemicals.
Toothpaste
The atomic mass number for fluorine is 18.9998, rounded to 19. Most fluorine is 19F but some is 18F with a half-life of 109.77 minutes.
fluorine
Not in all uses. Some inorganic compounds of fluorine are used in toothpaste for example. Fluorine compounds are contained in the teeth and in the bones of people and animals. PURE fluorine is an extremely deadly poison that is very corrosive and explosive, such as when it contacts anything containing hydrogen. Fluorine will take your hide right off, blind you, and kill you. When a person asks the question "Is fluorine a poison?", they MEAN pure fluorine, so answering the question in any other way is rather silly. Some other pure elements that are deadly poisons include chlorine, sodium, magnesium, cesium, potassium, bromine, cadmium, mercury, phosphorus, selenium, tellurium, radon, and plutonium. Don't mess around with any of these.
Fluorine can be found in toothpaste and water fluoridation to help prevent tooth decay. It is also used in non-stick coatings on cookware and in the production of some medications. Additionally, some refrigerants and solvents contain fluorine compounds.
Reacts with Oxygen and Fluorine
Table salt, which is sodium chloride, does not naturally contain fluorine. However, some table salts may be fortified with iodine to prevent iodine deficiency in the diet. Fluorine is not typically added to table salt.
Hydrogen reacts with fluorine to form hydrogen fluoride. This can also be hydrofluoric acid if some moisture is present.
