Answer:
At times, experimental results completely upended the prevailing theory and researchers had to come up with an entirely new model of the atom in order to explain the results. In some cases, new theories were established. Surprising new information gleaned from a failed photography experiment led to the discovery of radioactive particles.
Explanation:
The scientific model of the atom has changed over the centuries due to new discoveries.
An atom refers to an indivisible particle that's composed of protons, neutrons, and electrons. There are different atomic theories such as Thomson's plum-pludding model, Dalton's model, Rutherford's atomic model, Bohr's model and Schrodinger's model.
It should be noted that models are used by scientists to make predictions. There are certain scenarios whereby the result of an experiment doesn't conform with the existing model. In such a situation, a new model will be made to explain the new evidence. For example, a failed photography experiment led to the discovery of radioactive particles.
