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

I’m no scientist but consider this…

I read your assumption as, heavy metals would be pulled to the center because of their weight. I am assuming that the center of the earth is neutral, as gravity is not created by the center but the whole earth mass. At the center an object would be pulled in all directions and therefore exert the equal and opposite force (weight) in all directions and would appear to be weightless.
