Available resources
Atomic Theory & Radioactivity
Investigate how atomic models changed in response to experimental evidence, compare isotopes, model alpha, beta and gamma decay, and explore radioactive half-life using…
Periodic Table & Reactivity Challenge
A randomised challenge testing periodic table position, chemical families, valence electrons, noble-gas stability and reactivity trend predictions.
Periodic Table & Reactivity Explorer
Explore how atomic structure, electron shells, groups and periods explain patterns in the periodic table and help predict the properties and reactivity of metals,…
Periodic Table & Reactivity Investigation
A guided investigation where students connect groups, periods and valence electrons to chemical families, noble-gas stability and reactivity trends in alkali metals and…
Radioactivity & Stable Atoms Investigation
A guided investigation where students connect protons, neutrons and isotopes to the neutron-to-proton balance, predicting decay type and interpreting half-life.
