SUMMARY
The Earth's core primarily consists of iron and nickel due to their abundance in the Solar System and their physical properties. Heavier metals are less common and often exist in compounds with lower densities, preventing their accumulation in the core. The presence of radioactive elements like uranium and thorium contributes to the core's heat, while the formation of the core is influenced by the order of element fluidity during the planet's formation. Current hypotheses about the core's composition remain speculative, with no direct observations available.
