What cause scientists to change or replace the modern atomic theory?
If new observations do not fit exactly with the current theory.
Prediction need to change when?
observations change
When would scientists need to change a theory?
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
