Why is the center of the earth molten iron and not heavier metals, such as gold?

Question

I would assume heavier molten metals would be in the center of the earth. Is it possible that the center has different molten metals on top of each other with a high concentration of iron on the outside of the core?

Answer 1

Earth’s center is solid. Mostly iron and nickel. Other heavy metals are likely in the mix. The composition reflects the abundance of the metals that formed our solar system.
