Shown in the figure below is a re-creation of the Rutherford experiment. The "target" (green) nucleus...
In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +2e and mass 6.64 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is in a very small nucleus, with electrons in orbit around it. Assume an alpha particle, initially very...

An alpha particle, having charge ÷2e and mass 6.64 × 10-27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is In a very small nucleus, with electrons in orbit around it. Assume an alpha particle, initially...

In the Rutherford Gold Foil experiment, alpha particles (with a charge of 2e and a mass of 6.645×10-27 kg) were shot directly at a thin sheet of gold with a speed of 1.017×107 m/s from very far away. They found that most of the time the alpha particles traveled straight through the thin sheet, but sometimes they would bounce directly back. The alpha particle would only bounce back when its path was aimed directly at a gold nucleus (otherwise it...
