Front

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

Back

It becomes a completely different atom, with different properties.

50_25Y

Front

Define Alpha radiation.

Back

Alpha radiation consists of helium nuclei (2 protons and 2 neutrons) emitted from a radioactive source.

Front

Define Beta radiation.

Back

Beta radiation consists of high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

Front

Define Gamma radiation.

Back

Gamma radiation is a form of electromagnetic radiation of high frequency and energy, emitted from a radioactive nucleus.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy atomic nucleus into two lighter 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.
