John Dalton
Thought that each element is made of atoms that are basicly all alike. He also thought that different elements have atoms of different mass. -
J.J. Thomson
Discovered elctrons and that a atom is positivly charged. His model can be disrciped as a muffin with scattered components. -
Hantaro Nagaoka
The atom has a large sphere in the center and is positivly charged. A metaphor to his model is like the planets revolving around the sun. -
Erenest Rutherford
Atoms are relativly empty space adn the electrons orbit around a positivly charged nucleus. -
Erwin Shroedinger
The nucleus contains protons and neutrons , and the electrons look like spinning clouds. -
Present day model
Electrons make a negativly charged cloud around the nucleus. It is nearly impossible to giv e a location of a given electron.
