What did thomson’s model of the atom include that dalton’s model did not have? a nucleus energy levels electron clouds smaller particles

Option (d) is the correct answer.

Explanation:

J.J. Thomson discovered that there are positive and negative particles present inside an atom. These particles are smaller than the size of the atom.

Model of J.J. Thomson for atom is known as the plum pudding model.

Whereas John Dalton proposed that all matter is made up of atoms. But he did not explained what these atoms are in actual.

Hence, we can conclude that Thomson’s model of the atom include smaller particles that Dalton’s model did not have.

i think it is non rem sleep
