Fluorine-18 is created from bombardment of O-18 with a hydrogen ion in an accelerator or in a reactor with neutron bombardment of Lithium-6 followed by the resultant tritium combining with O-16 to form F-18. There may be places in the universe where a little of this may be going on but for all purposes it is not naturally occurring on Earth.
As for "abundance"... it depends on how many cyclotrons and target O-18 are used each day to create F-18 for FDG scanning and F-18 bone scanning.
With a 110 minute half-life, any given day's dose is gone by the next...

Where on earth do you find fluorine?
Fluorine or Fluorite is natural to the earth's crust and is found in rocks, coal and other natural formations. It is the Earth's thirteenth most abundant element and around four million tons of it are extracted yearly from mines in Western Europe, China and Mexico.
What type of bond is formed when you combine fluorine and fluorine?
Fluorine seems a likely answer
Which is bigger fluorine or hydrogen?
Fluorine.
Is fluorine a reactive or stable element?
fluorine stable fluorine diatomic is unstable
How fluorine is made?
Fluorine is an element. It occurs naturally.
Most abundant halogen?
The most abundant halogen in Earth's crust is fluorine. The most abundant halogen on Earth's surface for example is chlorine.
What is the most abundant isotope of oxygen?
There is only one abundant isotope of fluorine and that is 19FFluorine-19 is the most common isotope, its abundance is classed as 100% because no other Fluorine isotopes exist in significant quantities. It is also the only stable Fluorine isotope.
How abundant iodine is?
Iodine is very less abundant compared to fluorine and chlorine and it is found in seawater also with chlorides,bromides etc and certain forms of marine life also contain Iodine in their systems.Eg Seaweeds
What year was fluorine created?
Fluorine was discovered by Karl Scheele in 1771, recognized as a halogen in 1825, and included in Mendeleev's periodic table of 1869. Fluorine is so active that it existed only in compounds and all efforts to isolate the element failed. Because of its high corrosiveness/toxticity, early fluorine chemists died from fluorine poisoning and the element was dubbed "Tiger of Chemistry." Fluorine, from Latin "fleure" meaning to flow, is the 13th most abundant element in the earth's crust and the most reactive of all elements--it even forms compounds with noble gases.

Which element has the largest radius in the halogen family?
Astatine, with a molecular weight of 210 amu.
Which has a greater electronegativity fluorine or francium?
Fluorine.
What is is the most active nonmetal?
Fluorine
How many elements are in a fluorine atom?
Fluorine is an element, s an atom of fluorine contains only one element - fluorine. However, the fluorine molecule consists of two atoms of fluorine.
How many atoms of fluorine in barium?
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
How fluorine reacts with cold water?
fluorine reacts with water veryviciously the chemical equation for it is fluorine + oxygen = fluorine oxide
What is the valency of fluorine?
The valency of fluorine is -1.
