Properties of transition metals (chemistry only)

Question

A. They are used as catalysts.
B. They are used as insulators.
C. They are used as fuels.
D. They are used as solvents.

Answer

The correct option is They are used as catalysts..

Explanation

The correct option is They are used as catalysts.. They are used as catalysts. is correct because it directly supports the approved learning objective to (chemistry only) Describe that many transition-metal compounds are coloured. This is tested in the subtopic Typical properties within Properties of transition metals (chemistry only), so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Typical properties precisely. Repair marker 96aa31ca keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.

Common mistake

Misunderstanding Coloured Compounds

Students often think that all transition-metal compounds are coloured, rather than understanding that many, but not all, are coloured.

Emphasize that while many transition-metal compounds exhibit colour due to their electronic structure, it is not a universal property for all compounds of transition metals.
