Patterns in the periodic table

This unit explores the periodic table, including the principles behind Mendeleev's design, the arrangement of elements into periods and groups, and the classification of metals and non-metals. It examines how the physical and chemical properties of elements predict reaction patterns.

Prior knowledge

  • All matter is made up of atoms.
  • Each element is made up of just one sort of atom.
  • Each element is made of a different type of atom.
  • Each element has particular physical properties.
  • Each element has particular chemical properties.
  • Metals are good thermal and electrical conductors, they are strong, shiny, malleable and ductile.
  • Non-metals are normally poor thermal and electrical conductors, they are not strong, and are dull and brittle.
  • Metals are found on the left side and in the middle of the periodic table, non-metals on the right side.
  • Each element has a chemical symbol of which the first letter is always a capital.
