Answer:
The heaviest element which can be fused in the 'core of a star is iron'.
Step-by-step explanation:
- Throughout a stars lifetime, there is a 'continuous fusion reaction' going on in its core.
- This reaction is fed by various elements present near the core of the star.
- These elements can most probably be hydrogen, helium, carbon, oxygen, nickel, and iron.
- When the star runs out of one elements, it uses the other to continue the fusion reaction going on in its core.
