  Did I miss something in school? Plenty of things heavier than helium aren’t metal. Boron, carbon, nitrogen, oxygen, fluorine, neon…

    In astronomy, nearly everything is hydrogen or helium. Like, over 98% of all matter is H or He. So it’s very useful to be able to talk about H, He, and “everything else”. They call that everything else “metals”.

      Some stellar atmosphere models also add “alpha”, which provides an extra knob for the abundance of alpha-capture elements. If you need anything more than that, you’re doing some niche astrophysics.

    Not for astrophysicists. They call basically everything a “metal”. Of course they know it’s wrong. But they keep doing it to annoy the chemists, I think.

      We also label things as prime to trick mathematicians into thinking a derivative has occurred

  Anything metal between two pieces of different metal is a sandwich
