Fission vs Fusion

Front

What is nuclear fission?

Back

Nuclear fission is a process where one larger atom nucleus decays and breaks into two or more smaller atom nuclei, releasing energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two smaller atom nuclei combine to form one larger atom nucleus, releasing energy.

Front

What is the primary reason scientists study nuclear fusion?

Back

To make energy for people to use.

Front

What type of radiation is known to cause biological damage?

Back

Gamma ray.

Front

What happens during nuclear fission?

Back

A larger atom nucleus splits into two or more smaller atom nuclei.

Front

What is an example of a fusion reaction?

Back

The fusion of hydrogen nuclei to form helium in stars.

Front

What is the main difference between fission and fusion?

Back

Fission splits a large nucleus into smaller ones, while fusion combines small nuclei into a larger one.

Front

What is a common use of nuclear fission?

Back

Nuclear power plants use fission to generate electricity.

Front

What is a common use of nuclear fusion?

Back

Fusion is the process that powers the sun and other stars.

Front

What are alpha particles?

Back

Alpha particles are positively charged particles made of two protons and two neutrons, emitted during some types of radioactive decay.
