6.4.1 Atoms and isotopes

You will need to use a combination of the materials we have collected here to enable you to succeed. The most important factor will always be your effort. Use the knowledge of your teacher, attend revision sessions, ask when you need help. Most importantly of all, stay confident! You can do this!

Learning Checklist & Knowledge Organisers

6.4.1 Atoms and isotopes (Higher Only)

Describe the basic structure of an atom and how the distance of the charged particles vary with the absorption or emission of electromagnetic radiation
Define electrons, neutrons, protons, isotopes and ions
Relate differences between isotopes to differences in conventional representations of their identities, charges and masses
Describe how the atomic model has changed over time due to new experimental evidence, inc discovery of the atom and scattering experiments (inc the work of James Chadwick)
