This PowerPoint lesson activity will help you to introduce learners to names and formulas for non-metal compounds and the chemical information they contain. The activity includes:

  • how the name of a substance can indicate the elements in a compound
  • understanding the prefixes mono-, di-, tri- etc.
  • compounds with common names that need to be learnt, eg methane
  • links between the name and the chemical formula and how to deduce one from another
  • try-it-for-yourself exercise, with answers

The try-it-for-yourself exercise is also available as an editable handout.

This resource accompanies the Education in Chemistry article How to teach chemical formulas and equations.
