Detailed explanation-1: -What can you conclude from the fact that scientists continue to update the atomic model? new information continues to be discovered. old information is completely useless. scientists did not have any information about atoms until a few years ago.
Detailed explanation-2: -This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence.
Detailed explanation-3: -Conclusion. According to Dalton’s atomic theory, all matter is made up of atoms, which are indestructible and indivisible building blocks. While an element’s atoms were all the same size and mass, various elements possessed atoms of different sizes and masses.
Detailed explanation-4: -The atomic model changes over time because the atomic model was based on theories and discoveries.
Detailed explanation-5: -Bohr’s model (1913) Niels Bohr improved Rutherford’s model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. The Dalton model has changed over time because of the discovery of subatomic particles .
