My name is J.J Thomson. I named my model The "Plum Pudding". Negative charge (electrons) spread out in a "sea" of positive charge. Cathode ray tube experiment.
I am Ernest Rutherford , and I discovered the nucleus. Their is a positive charge in the center. Atoms are mostly empty spaced. - Gold Foil Expriment.
My name is Neils Bohr. Electrons in orbits around the nucleus. Based on the energy the electron has. Still used to draw atoms. Flame test and atomic emission experiment.
