Is iron heavier than gold

Answer 1

Gold has many more protons and neutrons in the nucleus of each atom than iron does. So each gold atom weighs almost four times as much as each iron atom. The extra electrons in the gold atoms do make the atom a little bigger than an iron atom, but not a whole lot. So there are nearly as many gold atoms as iron atoms per volume, but each gold atom weighs a lot more. So gold ends up denser.

Answer 2

Iron is heavier than gold, in physics and literature and Middle Earth too :}
