Ernest Rutherford's Gold Foil Experiment

For this blog assignment I decided to look deeper into the Experiment that founded the nucleus, the Gold Foil Experiment. When we were going over this experiment during class, I didn't really understand why the alpha particles were deflected and how this founded the discovery of the nucleus. If you click on the link to my glogster below, all you chemistry dreams will come true! Enjoy!

Here is a link to my Glogster!

Here is also a Youtube Video that further explains the Experiment:

After conducting my research I realized that the significance of this experiment was that current plum pudding model of the atom was incorrect and that because of the waythat the alpha particles bounced off the gold foil showed that the majority of the mass of the atom was concentrated in one small area (the nucleus). Since most of the positive particles continued on their original path undeflected, Rutherford assumed that the rest of the atom was made up of empty space. Rutherford termed his discovery "the central charge," and it is now called the nucleus. Rutherfords discovery lead to the Bohr model of the atom and the developement of nuclear physics.
