Front

What process is responsible for the formation of all elements except hydrogen?

Back

Nuclear fusion is responsible for the formation of all elements except hydrogen.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, releasing energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic radiation emitted from a nucleus during radioactive decay.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is a radioactive isotope?

Back

A radioactive isotope is an isotope of an element that is unstable and can decay, emitting radiation.
