This worksheet explains how isotopes can become unstable and
investigates the number of protons and neutrons in example
isotopes. Students then use the ANSTO Atom Builder online to
construct isotopes and record if they are stable or unstable.
The Australian Nuclear Science and Technology Organisation is
acknowledged for creating and proving access to the Atom
Builder App.
