Fluorine is a chemical element and it is the lightest halogen. It exists as a highly toxic pale yellow diatomic gas at standard conditions. Also it is the most electronegative element and extremely reactive. Almost all other elements, including some noble gases, form compounds with fluorine. It is also found in products such as toothpaste.
Fluorine was likely formed billions of years ago in now dead stars like our sun. Like other heavier elements, such as gold. The origins of Fluorine have been somewhat of a mystery. There have been three main theories about where it was created. The findings now presented support the theory that fluorine is formed in stars similar to the sun but heavier, towards the end of their existence.
Different chemical elements are formed at high pressure and temperature inside a star in a process known as Nucleosynthesis. Fluorine is formed towards the end of the star’s life, when it has expanded to become a red giant.
The fluorine then moves to the outer parts of the star and is cast off with the outer parts of the star forming a planetary nebula. The elements, including fluorine, that are thrown out and form new star/planets.
It’s cosmic building and recycling on a universal scale.
