Question
- A. Electrons move to the second energy level
- B. Electrons leave the atom
- C. Electrons occupy the outer shell
- D. Electrons remain in the first energy level
Answer
The correct option is Electrons move to the second energy level.
Explanation
The correct option is Electrons move to the second energy level. Electrons move to the second energy level is correct because it directly supports the approved learning objective to explain that electrons occupy the lowest available energy levels or innermost shells first. This is tested in the subtopic Electronic structure within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes, 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 Electronic structure precisely. Repair marker 24f5f7d5 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Electron Shells
Students often think that electrons can occupy any energy level without following the order of filling from the lowest energy level first.
Emphasize that electrons must fill the lowest available energy levels or innermost shells before moving to higher energy levels.
