Front

What are alpha particles?

Back

Alpha particles are positively charged particles made up of 2 protons and 2 neutrons.

Front

What are beta particles?

Back

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

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 neutron?

Back

A neutron is a subatomic particle found in the nucleus of an atom, with no electric charge.

Front

What is a proton?

Back

A proton is a positively charged subatomic particle found in the nucleus of an atom.
