Behold the magnificent disciplinary divide! While chemists are busy categorizing 118 elements into a fancy periodic table with color-coded families, astrophysicists are like "nah, just throw everything after helium in a bucket labeled 'metals'" and call it a day! 🚀
In stellar classification, astronomers really do lump most elements heavier than helium as "metallicity" because they're too busy contemplating black holes to bother with your fancy electron configurations. It's like going to a five-star restaurant and ordering "food" instead of specifying the dish. Cosmic simplification at its finest!
