Chem help, again please? :P?

Rutherford thought that the alpha particles that he passed through the gold foil would just go straight through without being disturbed. What he found on the other hand was that most of the particles went through undisturbed but some bounced off the gold foil at very large angles. This lead Rutherford to believe that atoms are mostly empty space with a nucleus (central core of atom). His model had the nucleus where all the positive charges, and most of the mass is located. and then electrons distributed around the nucleus, occupying almost all the volume of the atom.
