Nuclear Fission and Fusion

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei, releasing a significant amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining two small atomic nuclei to form a larger nucleus, also releasing energy.

Front

What is an example of an uncontrolled fission reaction?

Back

An example of an uncontrolled fission reaction is an atomic bomb.

Front

Where does nuclear fusion occur naturally?

Back

Nuclear fusion occurs naturally in the sun.

Front

What is a major drawback of nuclear fission reactors?

Back

A major drawback of nuclear fission reactors is the difficulty of achieving safe disposal of radioactive waste products.

Front

What is a half-life?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay.

Front

What type of reaction powers the sun?

Back

The sun is powered by nuclear fusion reactions.

Front

What is gamma radiation?

Back

Gamma radiation is a type of high-energy electromagnetic radiation emitted during radioactive decay.

Front

What is the primary fuel used in nuclear fission reactors?

Back

The primary fuel used in nuclear fission reactors is uranium.

Front

What is the difference between controlled and uncontrolled fission?

Back

Controlled fission occurs in nuclear reactors where the reaction is regulated, while uncontrolled fission occurs in atomic bombs.
