- 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 that Group 1 elements have one electron in their outer shell. 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 8bb8fbbb keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Outer Electrons
Students often think that Group 1 elements have more than one outer electron.
Remember that Group 1 elements, such as lithium, sodium, and potassium, each have exactly one electron in their outer shell.
