A cubic foot of iron would weigh 491 lb. A cubic foot of copper would weigh 559 lb. Silver is even denser than copper, at 655 lb for a cubic foot. Gold is really heavy at 1206 lb for a cubic foot.
Furthermore, is gold the heaviest metal?
Answer 5: I believe the heaviest naturally occurring metal in terms of atomic weight is plutonium. However, osmium is the densest metal followed by a closed second place with iridium. Here is the wikipedia page on osmiun that you might find interesting.
Is gold heavier than iron?
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.
