Question

which is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle? (1 point)
○ helium
○ iron
○ uranium
○ beryllium

Explanation:

Nuclear fusion in large stars releases energy up to the formation of iron, as iron has the highest binding energy per nucleon. Fusion of heavier elements requires energy input, so stars cannot produce heavier elements like uranium via fusion at the end of their life cycle. Helium and beryllium are much lighter and formed earlier in stellar fusion processes.

Answer:

B. iron
