Question

Describe the contribution that Rutherford made to the development of the atomic
theory?​

Answer 1

Answer:

By alpha particle scattering experiment:

Rutherford found out an atom has positive charges

and the positive charges are concentrated in the center of the atom

Answer 2

Explanation:

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
