• Decay of radioactive elements into stable isotopes.

• Conversion of matter into antimatter.

• Combining light atomic nuclei to form a heavier nucleus.

What is the main difference between nuclear fission and nuclear fusion?  

• Fission combines smaller atomic nuclei smaller to form a larger one, while fusion splits them apart.

• Fission occurs in the Sun, while fusion is used in nuclear power plants.

• Fission splits atomic nuclei into smaller parts, while fusion combines smaller nuclei to form a larger one.

• There is no difference between them.
