Frequently Examined

Transition metals are regularly examined, particularly in questions comparing them to Group 1 metals, and in context questions about catalysts. Common question types: compare the properties of a transition metal with those of an alkali metal (4 marks); explain why a transition metal is used as a catalyst (2 marks); give the colour of a named transition metal compound (1 mark); state the charge of iron ions in a given compound (1 mark). Transition metals also reappear in the Haber process (rates of reaction), electrolysis, and organic chemistry topics.

Edexcel 1CH0: Examined in Paper 1 (1CH0/1). Edexcel tests transition metals through comparison questions (higher density, higher melting point, variable oxidation states, coloured compounds vs Group 1 metals) and catalyst context questions. The use of iron in the Haber process and copper in electrolysis are recurring examples. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
