-
He proposed an atomic theory based upon measurable properties of mass.
-
Determined the mass ratio of an electron. Studied canal rays.
-
Probed atoms in a piece of thin gold foil to determine that the nucleus was dense small and positively charged. He assumed that the electrons were located out of the nucleus
-
He made an explanation of atomic structure to make an understanding on the periodic table of elements. Made an atomic model made out of successive orbital shells of electrons
