A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes
Question
- A. It suggests that electrons are in fixed orbits around the nucleus
- B. It proposes that atoms are indivisible
- C. It states that all atomic mass is distributed evenly
- D. It claims that electrons have no charge
Answer
The correct option is It suggests that electrons are in fixed orbits around the nucleus.
Explanation
The correct option is It suggests that electrons are in fixed orbits around the nucleus. It suggests that electrons are in fixed orbits around the nucleus 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 7ca9f01c 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.
