Question

Explain how the atomic theory was modified from

Dalton's theory to Rutherford's. Include an
explanation of why the theory was modified.

Answer 1

Answer: Thomson's showed that atoms contain smaller particles, so it was important to change the theory of daltons. Rutherford found that most of of an atom is hollow and in the middle of an atom is concentrated energy. This contributed to the revision of the plum pudding model.
