Is it possible Earth’s core could be made out of silver and gold? Why or why not?

Here’s what we do know:

1. The Earth’s overall specific gravity is 5.5.
2. The SG of the earth’s crust averages around 2.8.
3. Chondrites have an SG of 5.5, so it is logical to assume that the Earth and chondrites were both derived from the same primordial mass.
4. Chondrites have a much higher concentration of Fe and Ni than the Earth’s crust, therefore, the Earth’s core must be composed of Fe and Ni.
5. The Earth has a magnetic field, and as far as we know only Fe and Ni have sufficient magnetic susceptibility
6. p and s earthquake waves tell us that the earth’s core is solid.

So the most logical conclusion is that the earth’s core is composed principally of iron, with about 10 percent alloy of oxygen or sulfur or nickel, or perhaps some combination of these three elements.

its made entirely out of either. the earth’s core is mostly composed out of nickel and iron because they are the most balanced elements in terms of nuclear forces and repulsive electrostatic forces. if it was made out of gold or silver, for one thing there would be no magnetic field. as such, many animals would find it much more difficult to migrate

Sum is right about the magnetic field. The earth’s magnetic field is believed to come from the liguid iron nickel outer core. In addition, we have a rough mass which calculated to be roughly that of iron so gold is too dense.
