    How about somewhere a lot further away?

    The elements found across our solar system, on Earth, and even in our own bodies originated inside the cores of stars, which released them in stellar explosions.

    But the mystery of how fluorine was created within these stars has persisted.

    Fluorine occurs naturally in the earth's crust where it can be found in rocks, coal and clay. Fluorides are released into the air in wind-blown soil.

    Perhaps it can only be found in compounds due to its extreme ability to attract
    electrons (it is the most electronegative element). It just does not naturally exist in pure form.

    Off-topic posting again, I see.

    Any fool can look up the properties of fluorine on the web. None of this has any relevance to the question being asked, which is about nucleosynthesis of F in stars and hence its cosmic abundance.

    I did not introduce it. I merely posted what is known about fluorine.

    I followed it up with a speculative proposition that it may be very difficult to trace its origin in pure form due to its volatility and affinity to bond with just about every other atom in existence.

    After all these years you still do not grasp the purpose of a public forum, where information is shared not just with knowledgeable posters but with any and all non-posting readers, who might be curious why fluorine is so hard to trace.

    Except for your insufferable derision, you seldom contribute ANYTHING of value. At least I try to share and provide positive input of what I learn myself for the first time.

    But you just have to flount your superior position, don't you?

    Flaunt.

    Nothing to do with superiority, save that, unlike you, I have some idea of what the point of a discussion is and thus what may be relevant to it. The chemistry of fluorine is nothing to do with its cosmic abundance.

    Thank you for the correction. Very appropriate.

    As I said, I did not introduce the subject. I merely responded.

    As to Fluorine.

    Are Teeth Considered Bones?

    Seems to me that fluorine (fluoride) is very important in the abilitie to chew and digest a variety of foods without having to deal with decay that shortens life spans.

    This is one of the facts posited by Robert Hazen, and Louis Allamandola from NASA studies these clouds and has found several biochemical compounds in these dynamic objects.

    I think they just run out of articles to write sometimes and try to make everything sound like a great break through.

    The earliest stars were mainly hydrogen since that's all that initially existed (along with some helium and trace amounts of lithium). The early stars were large and short-lived. The fluorine seems to be bound with hydrogen and it says that it was assumed that it came from these early stars in one part of the article.

    In another part "it was totally unexpected".

    I don't think we have learned much here have we?

    Aside.

    Fluorine is the name of my MARVEL Super Hero.

    I did read that flourine (in some form)is an fairly important chemical in bone formation. If my assumption that a chromosomal fusion was causal to increased brain size, fluorine (in some form) might have been instrumental in bone growth and may well have been part of the evolutionary process of increased skull size to accommodate that gradually growing brain.

    Apart from that, fluorine based products like chlorofluorocarbons and hydrochlorofluorocarbons are an extremely important threat to the presence of UV defensive ozone layer in the atmosphere. This was demonstrated in the destruction of the Ozone hole at the poles. My guess is that even as this chemical does not exist in free form it is a very important part of atmospheric conditions. Moreover due to its ability to combine with almost everything fluorine is already present in biochemical compounds in deep space Nebulae.
