Democritus major discovery was that he named atoms. He also thought about crafting his idea because no one believed him.The model of the atom was made up of small particles that cant be divided sets of properties.

J.J Thomas made a major discovery and what he discovered was life hanging. He discovered that atoms were made up of small particles. He used a device to conclude atoms to rove they were made up of small particles. The model he used was negative charges scattered with a positive charge.

James chadwick, he discover a major thing and it was called neutrons. he wanted to prove and show that neutrons existed and were real. The model that he made was neutrons in the nucleus.

Ernest Chadwick made a major discovery and he discovered the well know nucleus. In the experiment used, he used alpha particles to prove that the nucleus existed. the model he made was all of the atom's positive changes in the nucleus.

John Dalton made a major discovery which was the theory of atoms. John Dalton also studied gases and he studied air to prove the theory of the atom. The model that he used was made with atoms that are elements.

A major discovery made by Erwin Schrodinger was a mathematical equation motion of the nucleus. He use his cat and poison and put both into a box to see if he could tell if the cat died. The model of the atom was a electron cloud model.

Werner Heisenberg's major discovery was he couldn't know the speed and the position. his experiment was not used but his model was electrons move around the nucleus in an uncertain path.

Niels Bohr major scientific discovery was that electrons were made like planets. his experiment that he used was with light and electrons.The model he made was electrons move at speed around the nucleus in a fixed orbit.
