Answer:
The discoveries made by earlier scientists led to the development of modern atomic theory. The modern atomic theory claims that each element is made up of atom of different kind. It explains that atoms are made up of sub-atomic particles.
Claim: Works from earlier scientists helped in the formulation of the atomic theory.
Evidences:
- John Dalton brought forward the theory that all matter is made up of atoms which are spherical and can move.
- J.J thomson discovered the electrons.
- Robbert Millikaan measures the charge on an electron.
- James Chadwick discovered the neutron.
Reasoning: All these evidences show that the discoveries of the earlier scientists led to the discovery of modern atomic theory.
