Short explanation
Explain that new experimental evidence can change or replace a scientific model. This objective belongs to The development of the model of the atom within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes for AQA GCSE Chemistry 8462. A strong answer should use change accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
