-
Theory stated that an atom is a positivley charged sphere with negatively charged electrons floating inside it. This reminded him of plum pudding so it was named the plum pudding model.
-
Determined the unit charge of an electron with his oil drop experiment. Thus allowing for the calculation of the mass of an electron and the positively charged atoms ( e=1.60x10 to the -19 power
-
Thoery described an atom as having a central positive nucleus surrounded by orbiting negative electrons.
-
Theory depicts an atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus
-
