Haemoglobin relies on iron atoms to bind oxygen molecules so they can be transported around the body

The Elements of Life is the first unit in the Salters Advanced Chemistry course. It reviews essential topics from GCSE-level chemistry and introduces new content, including:

  • the structure, properties, and behaviour of individual atoms
  • the interaction of atoms with electromagnetic radiation
  • the three main types of chemical bonding
  • chemical patterns in the periodic table
  • the shapes of molecules

Chemical Storylines sections[edit | edit source]

  • EL1: What are we made of?
  • EL2: Take two elements...
  • EL3: Where do the chemical elements come from?
  • EL4: Looking for patterns in elements
  • EL5: The molecules of life
  • EL6: Summary
