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 would pass through the empty space
between nuclei). This is actually how we discovered the gold
nucleus has 79 protons centered in the middle of the atom (rather
than spread out even through the atom).
What is the closest distance that this alpha particle could get
before bouncing back?

During a famous experiment in 1919, Ernest Rutherford shot doubly jonized helium nuclei (also known as alpha particles) at a gold foil. He discovered that virtually all of the mass of an atom resides in an extremely compact nucleus. Suppose that during such an experiment, an alpha particle far from the foil has a kinetic energy of 5.9 MeV. If the alpha particle is aimed directly at the gold nucleus, and the only force acting on it is the electric...

In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin gold foil. He unexpectedly observed a few of the particles scattered almost directly backward. This result was not consistent with then current models of atomic structure and led Rutherford to propose the existence of a very dense concentration of positive charge at the center of an atom—the atomic nucleus. The alpha particle has a charge of +2e and the gold nucleus...

In Rutherford's scattering experiments, alpha particles (charge = +2e) were fired at a gold foil. Consider an alpha particle with an initial kinetic energy K heading directly for the nucleus of a gold atom (charge =+79e). The alpha particle will come to rest when all its initial kinetic energy has been converted to electrical potential energy. Find the distance of closest approach between the alpha particle and the gold nucleus for the case K = 3.5 MeV

Consider an alpha particle deflected 90° by a gold nucleus (with a mass 50x the mass of the alpha particle).

In Rutherford scattering of alpha particles by a gold foil, large deflections can occasionally be observed because: a) a single alpha particle can be scattered many times in encounters with many atoms. b) the alpha particle can be deflected by the many atomic electrons of the gold. c) the wave nature of the alpha particles causes interference effects. d) none of the above.

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...
