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**.

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.
