Atoms that are heavier than iron are generally produced by ____________.
A) fission reactions within stars
B) fusion reactions within stars
C) the explosion of supernovae
D) the big bang

Question

Quizplus · Accepted Answer

Heavier atoms than iron are produced through a process called supernova nucleosynthesis, which occurs during the explosive deaths of massive stars. During this process, the energy released by the supernova is so immense that it causes the fusion of lighter elements into heavier ones. Therefore, option C, the explosion of supernovae, is the correct answer. Fission reactions within stars, option A, are responsible for the formation of elements up to iron. Option B, fusion reactions within stars, involves the fusion of lighter elements into heavier ones and does not contribute to the production of heavier atoms than iron. Finally, option D, the Big Bang, is responsible for the formation of basic elements such as hydrogen and helium, but not for the production of heavier atoms.
