Where did flourine come from?

Answer 1

Elements heavier than hydrogen were created over millions of years of nuclear fusion at the center of stars around the universe. As hydrogen nuclei are fused, they create helium atoms that can in turn also be fused under extreme amounts of pressure and temperature to make heavier elements, the cycle continues until elements such as iron are created at which point the star usually collapses. Elements more dense than this are created at the center of exploding stars under the pressure of one of the more powerful forces of the universe. Florine, being lighter than iron would be in the first category, having been fused from two other elements at the center of still active stars.

Answer 2

Fluorine is a naturally occurring element and is the 13th most abundant element in Earth's crust. It is produced through the nuclear fusion process in stars, specifically during supernova explosions. On Earth, fluorine is typically found in minerals such as fluorite and cryolite.

Answer 3

It's a fairly common element on Earth, for example calcium fluoride.

On a cosmic scale - it was formed from the primordial hydrogen and helium in stars which have since blown up.
