What is gamma radiation?

Back

Gamma radiation is a type of high-energy electromagnetic radiation emitted by radioactive decay of atomic nuclei.

What does the atomic number represent in an element's symbol?

Back

The atomic number represents the number of protons in the nucleus of an atom.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting an atom's nucleus into smaller parts, releasing a large amount of energy.

Front

What is nuclear fusion?

Back

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

Front

What happens to an atom when the number of protons changes?

Back

When the number of protons changes, the atom becomes a completely different element with different properties.

Front

What is a common use of nuclear fission?

Back

Nuclear fission is commonly used in nuclear reactors to generate electricity.

Front

What is the difference between mass number and atomic number?

Back

Mass number is the total number of protons and neutrons in an atom's nucleus, while atomic number is the number of protons.

Front

What is radioactive decay?

Back

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