We know that Jupiter and Saturn are made mostly of helium and hydrogen, but is this true for other systems and their gas giants too?

If we want to get kind of nitpicky, water, ammonia, and methane are also mostly hydrogen
No, by mass, they’re certainly not.
If we really get nitpicky, all the atoms in all of the elements are mostly made of empty space, aka nothing.
If we want to
keep the thread goingget even more nitpicky, empty space doesn’t exist, exactly. There’s just one big quantum field filling the universe.Although, future physics may change that picture.
The whole universe is mostly nothing, just like the stars and planets too.
