A-level Chemistry/OCR (Salters)/The Elements of Life

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

  • EL2: Take two elements...
  • EL3: Where do the chemical elements come from?
  • EL4: Looking for patterns in elements
