Question

Which element forms inside the core of high-mass stars?

iron

helium

hydrogen

carbon

Answer 1

Inside the core of high-mass stars, the element that forms as the final product of nuclear fusion is **iron**. During the later stages of a high-mass star's lifecycle, it undergoes fusion processes that create heavier elements up to iron, beyond which fusion does not release energy. This leads to the eventual collapse of the star and a supernova explosion.
