Ernest Rutherford. (aug 30, 1871 – oct 19, 1937)
-Created the Rutherford Model
-Discovered that the atom is mostly empty space.
-Believed that the atom had a core and called it the Nucleus.
-Positively Charged Core surrounded by electrons.
-He shot Alpha Particles at gold foil and discovered that most atoms passed through, therefore atoms are mostly empty. Thus, a "nucleus" is positive and holds most of the mass of an atom.
