Question
- A. Most atomic mass and positive charge are located in the nucleus.
- B. Atomic mass is evenly distributed throughout the atom.
- C. Positive charge is spread across the entire atom.
- D. Most atomic mass is found in the electron cloud.
Answer
The correct option is Most atomic mass and positive charge are located in the nucleus..
Explanation
The correct option is Most atomic mass and positive charge are located in the nucleus.. Most atomic mass and positive charge are located in the nucleus. is correct because it directly supports the approved learning objective to describe how the nuclear model placed most atomic mass and positive charge in 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 818de258 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding atomic mass location
Students often think that atomic mass is evenly distributed throughout the atom rather than concentrated in the nucleus.
Remember that the nuclear model shows that most atomic mass and positive charge are located in the nucleus, not spread out in the atom.
