For example, magnesium + oxygen, iron wool + oxygen, sodium + chlorine and copper foil + chlorine. Students complete target diagrams for different elements, state the number of electrons lost or gained to form an ion and add atom and ion symbols. They are then asked to organise the cards in the same way as the elements are arranged in the periodic table. Start with the idea that atoms form bonds to become more stable, like the noble gases.
