Question
- A. In the nucleus of the atom
- B. In the electrons surrounding the nucleus
- C. Evenly distributed throughout the atom
- D. In the empty space between the nucleus and electrons
Answer
The correct option is In the nucleus of the atom.
Explanation
The correct option is In the nucleus of the atom. In the nucleus of the atom is correct because it directly supports the approved learning objective to compare the plum pudding model with the nuclear model of the atom. 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 09bcae48 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Confusing Atomic Models
Students often confuse the features of the plum pudding model with those of the nuclear model, thinking they are the same.
To fix this, students should clearly outline the key differences: the plum pudding model depicts electrons embedded in a positively charged 'soup', while the nuclear model has a dense nucleus containing protons and neutrons, with electrons orbiting around it. Keep the correction anchored to The development of the model of the atom and avoid mixing it with nearby Unit 4.1 ideas.
