Metals and Non-metals
Your child will sort the material world by behaviour and link it to extraction and protection. This chapter usually carries about six marks, often reactivity-series reasoning plus an extraction or corrosion question. Learners test lustre, malleability, ductility and conduction, compare reactions with oxygen, water and acids to build the reactivity series, explain ionic formation through electron transfer, trace extraction from ores through enrichment, reduction and refining, and close with corrosion and its prevention by painting, oiling and alloying. Three misconceptions persist. Students ran
