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 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...

ver 8 Rutherford discovered the atomic nucleus by exposing gold foil to radium (an alpha emitter). Consider an alpha particle deflected 90° by a gold nucleus (with a mass 50x the mass of the alpha particle). If the kinetic energy K Eo of the alpha particle is redaced to K Eo after the collision, then how much energy is transfered into the gild muclens? Express this energy as a percentage of KEo) alpha ogol

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...

Use the following information to answer the next question. In the Rutherford alpha particle scattering experiment, some alpha particles were deflected coming straight back from the gold foil. When an alpha particle is emitted by the radium sample, it has a kinetic energy of 1.0 x 10-22 J. The electric potential energy of a charged particle in a radial electric field is modelled as kq192 Ер r Numerical Response 2. The maximum acceleration of an alpha particle at its closest...

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

Which statement reflects the results of Rutherford's gold foil experiments? Almost all of the alpha particles were deflected while passing through the foil. Almost all of the alpha particles passed directly through the foil. none of these Almost all of the alpha particles were deflected back in the direction from which they came. Almost all of the alpha particles sputtered gold atoms off of the surface of the foil.

Let f be the fraction of the detected alpha particles that were deflected through large angles (greater than 90 degrees). Would careful measurement of f would allow Rutherford to estimate the size of the nucleus of the gold atoms?
