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.
