what main features of dalton's atomic model was abandoned after thomson's discoveries?

Answer 1

Dalton thought the atom was indivisible. He thought it was a solid sphere. When Thomson discovered electrons coming from atoms, Dalton's model had to be discarded and another model of the atom formed.

Answer 2

Daltons Atomic Model

Answer 3

Dalton proposed that atoms were the elementary particles that all other matter was made up of. He thought of an atom of gold for example was a solid nugget that could not be divided any more.
Joseph Thomson announced seeing something in a cathode ray tube that was 1000 times less mass than a hydrogen atom. He called them corpuscles that made up of atoms. We know those corpuscles today as electrons.

Answer 4

Indivisible Solid Sphere Model

Answer 5

Dalton's now infamous "law of the conservation of filth" was abandoned. Although still unknown as to why. His "Law of the Conservation of Filth" to me is air tight, and goes thusly:
You cannot get any one item clean, without getting another item dirty. However, you can get everything dirty without getting one thing clean.
This Law still holds true, although the scientific community has abandoned it.

Answer 6

The main feature that was abandoned was the portion of the atomic model that directly correlates to the theory of relativity and the law of motion ---
