What is Fluorine?

  • The element Fluorine is a poisonous gas.
  • It usually exists as fluoride ion F- in aqueous solution
  • It remains in the air for long when attached to tiny particles.

Uses of Fluorine

  • Molecular fluorine and Atomic fluorine are used in semiconductor manufacturing for plasma etching, MEMs fabrication, and flat panel display production.
  • Chlorofluorocarbons are used extensively used in air conditioners and refrigerators.
  • Fluorides are also added to toothpaste to prevent dental cavities.
  • The metal could be used to map the circulatory system and any disorders.
  • Proposedly could be used in the optoelectric nuclear batteries.

Properties of Fluorine

  • Fluorine exists naturally in the earth’s crust and found in coal, clay, and rocks.
  • Hydrogen fluorides are released into the air by the industries through the processes of combustion.
  • 0.6 ppb of fluorine is present as organic chloride compounds and salt spray in the atmosphere.
  • The element has been recorded around 50 ppb in city environments.

Certain Facts About Fluorine

  • The 13th most abundant element in the Earth’s crust is Fluoride.
  • Fluorine is reactive with other elements which can combine with nearly any element on Earth.
  • Even water burn in fluorine with a bright flame along with finely divided metals like glass, ceramics, and carbon.
