This lesson explores what an atom is made of, the internal structure of an atom, and the properties of the particles that make an atom.
For next step we recommend the unit: Atoms and the periodic table.

This lesson explores how the internal structure of an atom can change to make isotopes or ions.
This lesson compares the plum pudding model with the nuclear model and explores the most significant experimental discovery that contributed to our modern model of the atom.
This lesson looks at the properties of four different forms of radiation and how we could experimentally determine which radiation an isotope is producing.
This lesson explores the changes that take place within the nucleus of an atom during radioactive decay and we will learn how to write radioactive decay equations using atomic notation.
This lesson explores the pattern behind the randomness of radioactive decay, how the half-life of an isotope can be determined and how the proportion of nuclei lost can be determined.
This lesson contrasts contamination and irradiation and explores some of the uses and dangers of radioactive sources by considering the properties of the radiations they produce and how they can be used in various situations.
This lesson will explore how we can use radioactive sources in a wide range of contexts, including within hospitals for imaging inside the body and treating disease.
This lesson will explore the processes of nuclear fission and nuclear fusion and how these important processes can, or could, be used for energy generation.
This lesson revises the Atomic Structure subject knowledge common to both GCSE Combined Science and GCSE Physics and gives an opportunity to work through some exam style questions.
This lesson revises the Atomic Structure subject knowledge on Half-life and the uses and hazards of radiation. This lesson also gives an opportunity to work through some exam style questions. It also covers Fission and Fusion which is only needed for the GCSE Physics course.
