A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes
Question
- A. It does not align with new experimental evidence
- B. It is too complex to understand
- C. It was created by a famous scientist
- D. It is widely accepted by the public
Answer
The correct option is It does not align with new experimental evidence.
Explanation
The correct option is It does not align with new experimental evidence. It does not align with new experimental evidence is correct because it directly supports the approved learning objective to explain that new experimental evidence can change or replace a scientific model. 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 aab07bc0 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Scientific Models
Students often believe that scientific models are fixed and cannot change over time.
Emphasize that scientific models are based on current evidence and can be modified or replaced as new experimental evidence emerges.
