Nuclear Reaction Quiz

What is nuclear fission?

• The process of splitting the nucleus of an atom into two or more smaller nuclei.

• The process of converting the nucleus of an atom into energy.

• The process of rearranging the nucleus of an atom into a different element.

• The process of combining the nucleus of an atom into two or more larger nuclei.

What is nuclear fusion?

• A process in which two or more atomic nuclei come together to form a single, more massive nucleus, releasing a large amount of energy in the process.

• A process in which two or more atomic nuclei collide but do not undergo any change or release of energy

• A process in which two or more atomic nuclei combine to form a smaller nucleus, releasing a small amount of energy

• A process in which two or more atomic nuclei split apart, releasing a large amount of energy
