Properties of transition metals (chemistry only)
Question
- A. Iron
- B. Sodium
- C. Calcium
- D. Bromine
Answer
The correct option is Iron.
Explanation
The correct option is Iron. Iron is correct because it directly supports the approved learning objective to (chemistry only) Use compounds of Cr, Mn, Fe, Co, Ni and Cu as examples of typical transition-metal properties. 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 c01a3c8b keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misidentifying Transition Metal Compounds
Students often confuse the properties of transition metal compounds with those of Group 1 metal compounds, leading to incorrect examples.
Focus on using specific compounds of Cr, Mn, Fe, Co, Ni, and Cu to illustrate typical properties of transition metals, ensuring to highlight their unique characteristics.
