Fluorine in solid form is a brown rock like this with crystals inside.
Fluorine crystals can have various colors.
This is the color of fluorine gas, in a tube.
Properties of Fluorine
- Boiling point - 85.03 K, -188.12 C, -306.62 F
- Melting point - 53.53 K, -219.62 C, -363.32 F
- State at room temperature - gas
Fluorine is a bright yellow (occasionally colorless or white) gas at room temperature. In gaseous form, it can only be seen if it is in long tubes.
Fluorine can be condensed into a liquid, which will be bright yellow in color.
Solid flourine is a brown crystallized rock. The crystals inside the rock can be various colors, such as yellow, purple, grey, and green. Fluorine is very hard to separate from its compounds and things that it is found in, so almost all of the time it is handled as a part of another substance. Pure fluorine has killed several scientists who tried to separate it.
History, Uses, and Concerns
Fluorine's most well known daily use is in toothpaste. Fluorine compounds are added to this everyday dental product to help prevent tooth decay. Fluorine salts were once used in metal welding, but today their primary use other than toothpaste is in the nuclear industry, where fluorine is used to insulate high-power electric transformers and separate uranium isotopes. Fluorine is also used in refrigerators and air conditioners.
Fluorine in drinking water and polluting the air from nuclear factories is of concern in America. Fluorine can be poisonous and dangerous if leaked from these factories and many fluorine compounds are dangerous to humans.
Fluorine is used in toothpaste and other dental products. The amount of fluorine in toothpaste is the reason that it has the warnings about not swallowing it.
Sodium Fluoride Pills
Sodium fluoride (NaF), a fluorine compound, is used in anti-cavity pills.
Fluorine in Water
This map shows red states where fluorine affects 75% of drinking water and blue states in which it affects less than 25%. Filters can help remove fluorine from water.
Three Common Flourine Compounds
Potassium fluoride is composed of potassium and fluorine and is used in organic chemistry.
Sodium fluoride is made when fluorine and sodium combine and it is used in pills for cavity prevention. It is also sometimes added to foods and drinks to help prevent any dental damages the food or drink may possibly have.
