Unstable Isotopes worksheet

Year Level(s) Years 7-10
Subject Area(s) Science General Science Chemistry
Topic(s) Atomic Science
Resource Type Worksheet

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.
