The Modern Uses

Fluorochlorohydrocarbon, which is created when some hydrogen atoms are replaced by fluorine and chlorine, is constantly used in air conditioning and refrigeration.

It is also used in rocket fuels because it has the ability to accelerate the rocket upward at a high speed.

Fluorine is often added into drinking water and toothpaste to prevent tooth decay.

For centuries, before fluorine was separated from other elements, fluorine salts called fluorides were used to weld metals and frost glass.

History of Fluorine
Around 1670 was the first recorded use of fluorine in etching glass.

In 1869, a chemist named George Gore tried to isolate a small amount of fluorine, but it reacted explosively with hydrogen.

In 1886, fluorine was successfully isolated by a French chemist named Henry Moissan. He acomplished this by using electrolysis.

Before World War II, fluorine wasn’t manufactured for public use. Then came the need for atomic bombs, and fluorine is used to separate uranium in atomic bombs.
Fun Facts
Fluorine originates from the Latin word fluere which means flow!
When fluorine is mixed with water, it reacts with a bright flame!
