Question

How did the discovery of neutrons change the atomic model?

Answer 1

People kept on finding out new things about the atoms so when nuetrons came into place they had to make a new model.

Answer 2

Rutherford concluded that Virtually all the mass of an atom is concentrated in a subatomic particles called nucleus. While the nucleus is named by James chadwick after Rutherford concluded it. After the discovery of the nucleus, we came to know that the nucleus of an atom consist of proton and neutron and the number of protons and neutrons in an atom determines that make number and mass number of an atom so some of the models and theory that were discovered before the discovery of neutron was proved to be wrong and after the discovery of neutron and many new theories and models were formed or created
