Chemical properties of fluorine - Health effects of fluorine - Environmental effects of fluorine
- Fluorine was discovered by Henri Moissan (FR) in 1886. The origin of the name comes from the Latin word fluere meaning to flow. It is a pale yellow to greenish gas, with an irritating pungent odour. Fluorine is a extremely reactive, flammable gas. It reacts violently with many materials. It is toxic by inhalation or ingestion.
- Fluorine is a chemical element with atomic number 9 which means there are 9 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.

Small amounts of fluorine are naturally present in water, air, plants and animals. As a result humans are exposed to fluorine through food and drinking water and by breathing air. Fluorine can be found in any kind of food in relatively small quantities. Large quantities of fluorine can be found in tea and shellfish.
Environmental effects of fluorine
When fluorine from the air ends up in water it will settle into the sediment. When it ends up in soils, fluorine will become strongly attached to soil particles. In the environment fluorine cannot be destroyed; it can only change form.

Fluorine is a pale yellow gas which is very toxic and poisonous but is essential for animals and humans to strengthen our bones and teeth. It is a very reactive gas which reacts even with noble gases, and it forms a large number of chemical compounds. The name of the chemical element is derived from the Greek word meaning flowing. Fluorine can not be found in its natural form as it reacts very fast. It was not produced until the middle of the 20th century, but in those times it became necessary for various projects involving nuclear energy. This element is also used in toothpaste and dental care products, as well as in producing some parts for electronic devices, for welding and processing glass, etc. In its natural form, fluorine exists in some types of clay, rocks, coal, and other sources.
Uses of Fluorine
Fluorine which is the most reactive element is used to produce uranium hexafluoride in the nuclear power industry. Today, fluorine compounds are mostly used in the pharmaceutical and agriculture fields. Dichlorodifluoromethane (a colorless gas with the formula Cl2CF2) is used as a coolant in domestic refrigerators and air conditioners. And hydrofluoroalkane (HFA) containing carbon, fluorine, and hydrogen, is used as aerosols in medicine. Hydrofluoric acid (HF) which is a solution of hydrogen fluoride in water, is used in industrial chemistry, glass finishing, cleaning, and research. Sodium fluoride, an inorganic compound with the formula NaF is commonly used in the production of pharmaceuticals. It is sold as tablets to prevent cavities. Sodium fluoride is also used in chemistry and in medical imaging too.
