Question
- A. Electrons are found in fixed orbits around the nucleus
- B. Electrons are randomly distributed within the atom
- C. Atoms are made up of indivisible spheres
- D. The nucleus contains only protons
Answer
The correct option is Electrons are found in fixed orbits around the nucleus.
Explanation
The correct option is Electrons are found in fixed orbits around the nucleus. Electrons are found in fixed orbits around the nucleus is correct because it directly supports the approved learning objective to describe how Bohr adapted the nuclear model by placing electrons at specific distances from the nucleus. This is tested in the subtopic The development of the model of the atom 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 The development of the model of the atom precisely. Repair marker f9d0302c keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Electron Placement
Students often think that electrons are randomly distributed around the nucleus rather than at specific distances.
Emphasize that Bohr's model specifically places electrons in defined orbits at certain distances from the nucleus.
