An interactive GCSE Chemistry lesson exploring how metals and non-metals differ in their position in the periodic table, physical properties and chemical behaviour. Students predict properties before completing a virtual practical investigation using copper, sulfur, aluminium, graphite and iron, testing appearance, bending/brittleness, electrical conductivity and state at room temperature. They use their observations to identify patterns, classify unknown samples and investigate graphite as an important exception. Animated atomic models then show why metals form positive ions by losing electrons, with sodium, lithium and potassium used to develop the link between electron arrangement and reactions. simopsis
