Question
- A. 2,4
- B. 2,2
- C. 4,2
- D. 2,6
Answer
The correct option is 2,4.
Explanation
The correct option is 2,4. 2,4 is correct because it directly supports the approved learning objective to represent electronic structure using diagrams for the first 20 elements. 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 776fced4 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misrepresenting Electron Shells
Students often incorrectly draw the electron shell diagrams for elements, placing too many electrons in the outer shell or not following the 2,8,8 rule for higher energy levels.
Ensure that the first shell holds a maximum of 2 electrons, the second shell holds up to 8, and the third shell also holds up to 8 for the first 20 elements.
