Atoms & Radiation

Welcome to the GCSE Physics Ninja Atoms & Radiation course.

These video lessons are based on question-and-answer flashcards. You can either make your own or download the printable flashcards from the shop.

What will I learn in this course?

When you have completed this course, you will be able to...

  • Explain the development of the nuclear model of an atom.
  • Use atomic notation to describe the structure of different atoms.
  • Understand that some atomic nuclei are unstable and can decay leading to radioactive emission.
  • Recall the properties of alpha, beta and gamma radiations.
  • Describe the effect of radiation on matter and safety issues.
  • Understand the concept of half life and carry out calculations.
  • Describe some practical uses of nuclear radiation in industry and medicine.
  • Explain the processes of nuclear fission and nuclear fusion.
  • Recall the stages in the life cycle of stars.
  • Understand that the elements we know today were formed in stars.
