⚗️ 1. Atomic Structure and the Periodic Table 8 lessons

Year 7 · KS3 | 📄 Go to Unit Page

In this unit pupils explore the structure of atoms and how elements are organised. They investigate atomic number, mass number, isotopes, and how the periodic table was developed and arranged by electron configuration.

  1. Atomic structure: very small electron mass
  2. Developing a model for atoms
  3. Atoms, elements and compounds
  4. Modern periodic table and electron configuration
  5. Atomic number and mass number
  6. Isotopes and relative atomic mass
  7. Relative formula mass
  8. Development of the periodic table

🧪 2. Atoms, Elements and Compounds 9 lessons

  1. Atoms and elements
  2. Properties of elements
  3. Metallic elements
  4. Molecular elements
  5. Common elements
  6. Compounds and their formation
  7. Chemical formulae
  8. Naming compounds
  9. A particle model of chemical reactions

🧫 3. Acids and Bases 7 lessons

Year 9 · KS3 | 📄 Go to Unit Page

  1. Acids and bases
  2. pH scale and universal indicator solution
  3. Practical: red cabbage indicator solution
  4. Chemical reactions: acid and metal
  5. Metal oxides and non-metal oxides
  6. Chemical reactions: neutralisation
