Question

the discovery of subatomic particles led to a revolution in the study of matter. Name the scientists who discovered these sub-atomic particles.

Answer 1

Electron JJ Thomson.
Proton Earnest Rutherford.
Neutron James Chadwick.

Answer 2

Sub-atomic particles are particles which are smaller than that of an atom.

The three main sub-atomic particles associated with an atom are:

1. Proton(positively charged)- discovered by Ernst Rutherford by the gold foil experiment

2. Neutrons(no charge)- discovered by James Chadwick

3. Electrons(negatively charged)- discovered by John Joseph Thomson by performing experiments with cathode rays
