Answer 1

Type in "Gold Foil Experiment" in the search box. This will give you plenty of links. The best one to follow are the powerpoint files.

This was the famous experiment conducted by Rutherford which changed the prior atomic model proposed by Thomson. Several ppt files explain this clearly with the matching images.

Answer 2

In 1911, Rutherford proposed a revolutionary view of the atom. He suggested that the atom consisted of a small, dense core of positively charged particles in the center (or nucleus) of the atom, surrounded by a swirling ring of electrons. The nucleus was so dense that the alpha particles would bounce off of it, but the electrons were so tiny, and spread out at such great distances, that the alpha particles would pass right through this area of the atom. Rutherford's atom resembled a tiny solar system with the positively charged nucleus always at the center and the electrons revolving around the nucleus.
