On this page you can discover the chemical properties of fluorine and information about fluorine and other elements on the periodic table such as chlorine, oxygen, neon or helium. You will also learn what fluorine is for and learn about its uses through its properties associated with fluorine such as its atomic number or the usual state in which fluorine can be found.

You will be able to see fluorine qualities such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in fluorine atoms and other properties.

For some elements, some of this information is unknown. In these cases we show the properties attributed to them.

Properties of fluorine

Elements from the group of halogens such as fluorine are presented as chemically active diatomic molecules. The name halogen comes from the Greek and its meaning is “salt forming”. They are halogen elements among which is fluorine, they are oxidants. Many synthetic organic compounds, and some natural organic compounds, contain halogen elements such as fluorine. These types of compounds are known as halogenated compounds.

The state of fluorine in its natural form is gaseous (non-magnetic). Fluorine is a pale green-yellow gaseous chemical element and belongs to the group of halogens. The atomic number of fluorine is 9. The chemical symbol for fluorine is F. The melting point of fluorine is 53.53 degrees Kelvin or -218.62 degrees Celsius or degrees Celsius. The boiling point of fluorine is 85.03 degrees Kelvin or -187.12 degrees Celsius or degrees Celsius.

Uses of fluorine

Fluorine is a highly corrosive pale yellow or brown gas. If you have ever wondered what fluorine is for , here is a list of its possible uses:

  • Some fluorine compounds (such as sodium fluoride, stannous fluoride, and sodium monofluorophosphate) are added to toothpastes to prevent tooth decay. They are also added hatibually to the water .
  • The most general anesthetics are derivatives of fluorine compounds.
  • Fluorine-18 is an artificial isotope that emits positrons and has a relatively longer half-life. This makes it ideal for use in positron emission topography.
  • Anti-reflective coatings contain fluorine compounds.
  • Fluorine can be used to manufacture plasma screens, flat screens and microelectromechanical systems.
  • Hydrofluoric acid is used to etch glass, usually light bulbs.
  • Fluorine is used in one step in the production of halons (fire extinguishing gases) such as freon.
  • Fluorine is used to obtain pure uranium from uranium hexafluoride.
  • Fluorine compounds are used in refrigeration and air conditioning systems.
  • Another fluorine compound is used in the electrolysis of aluminum . This process allows obtaining pure aluminum.
  • Some broad-spectrum antibiotics (which act against a wide range of bacteria) contain fluorine.
  • A large amount of the commercially produced fluorine is used to make sulfur hexafluoride . This compound is used as a dielectric (electrical insulator) in the electrical industry.

Atomic properties of fluorine

The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find fluorine within the periodic table of the elements, fluorine is found in group 17 and period 2. Fluorine has an atomic mass of 18.9984032 u.

The electronic configuration for fluorine is [He] 2s22p5. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. Fluorine’s mean radius is 50 pm, its atomic radius or Bohr radius is 42 pm, its covalent radius is 71 pm, and its Van der Waals radius is 147 pm. Fluorine has a total of 9 electrons whose distribution is as follows: In the first layer it has 2 electrons and in the second it has 7 electrons.
