Question

What did Rutherford’s model of the atom include that Thomson’s model did not have?

Answer 1

Rutherford’s new evidence allowed him to propose a more detailed model with a central nucleus. he suggested that the Positive charge was all in a central nucleus.

Answer 2

Answer with Explanation:

Atom=Smallest Particle present on earth

Subatomic Particle=Smaller than Atom(Electron +Proton)

Electron = -vely Charged Particle

Proton =+vely Charged Particle

In J.J Thompson Model of Atom , which is called Plum Pudding model ,Electrons and Protons that is Subatomic particles were uniformly Distributed inside the Nucleus of Atom.

But Rutherford Contradicted Thompson by saying that, Protons are fixed inside the nucleus and Electrons are moving in Elliptical path around the nucleus like the planets around the sun.This Model is Known as Planetary Model.
