Question
- A. Reactivity increases
- B. Reactivity decreases
- C. Reactivity remains the same
- D. Reactivity is unpredictable
Answer
The correct option is Reactivity increases.
Explanation
The correct option is Reactivity increases. Reactivity increases is correct because it directly supports the approved learning objective to explain why Group 1 elements have similar chemical properties. This is tested in the subtopic Group 1 within The periodic table, 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 Group 1 precisely. Repair marker 104be6d0 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Group 1 Properties
Students often think that Group 1 elements have similar properties because they are all metals, without considering their electronic structure.
Emphasize that Group 1 elements have similar chemical properties due to having the same number of outer electrons, which affects their reactivity and bonding.
