Sort these isotopes by whether they are most likely to undergo fusion or fission.

Hydrogen-3, Uranium-233, Plutonium-239, Hydrogen-1, Helium-3, Plutonium-241

Uranium-233 - fission

Plutonium-239 - fission

Plutonium-241 - fission

Hydrogen-3 fusion

Hydrogen-1 fusion

Helium-3 fusion

Explanation:

In nuclear fission, heavy nuclear disintegrate into smaller nuclei when bombarded with particles such as neutrons. Fission reaction is common among nuclei having a high atomic number such as plutonium and uranium.

Fusion occurs between two light nuclei such as hydrogen or helium. It involves the combination of two lighter elements to give a heavier element with the release of tremendous amount of energy.
