John Dalton
John Dalton was credited with discovering that common elements broke down into the same elements in the same proportions. This is important because we knew that atoms nucleus has the same proportions and larger things with the same elements. -
JJ Thompson
JJ Thompson made a huge discovery. He discovered the electron. The electron is the positive charge in atoms. This is important because we know what is inside the nucleus and what the positive charge is. -
Ernest Rutherford
Ernest Rutherford discovered that electrons orbit the nucleus at fixed energies and distances. This is important because we know what is in the space between the nucleus and outer part of the atom. It has electrons. -
Niels Bohr
Nails Bohr discovered that electrons orbit the nucleus at fixed energies and distances. This is important because it adds to Ernest Rutherford's discovery that they orbit the nucleus. He proved that they are at different energies and distances. -
Erwin Schrodinger
Erwin Schrodinger was the person to build on Neils Bohr's discovery and make the cloud model. This model shows that electrons do not move around a central nucleus in a fixed orbit. This is important because we know that electrons do not move around in a fixed orbit. They orbit freely around the nucleus. -
James Chadwick
James Chadwick was credited for discovering the neutron. This was such an important discovery because this is one of the three most important things in an atom. The three are neutron, electron, and proton. This helped us know what is in the nucleus as well.
