Rutherfords Gold-Foil Experiment?

Question

Describe Rutherford's model of the atom(got this part).How does this model explain the deflections of a beam of alpha particles aimed at the sheet of gold-foil?

Answer 1

protons and nuetrons-in nucleus---why is deflected
electrons take up most of the volume of the atom
a lot of empty space as well----why it went through

Answer 2

this experiment was used to determine that the atom is mostly empty space and that there is a dense nucleus. Alpha particles (invisible) were aimed at a thin piece of gold foil and the foil is surrounded by a phosphor screen that detects alpha. Most of the particles went through the gold foil proving that the electron is mostly empty space. ONce in a while an alpha pariticle would hit a dense nucleus in the foil and deflect.

Answer 3

A slightly more specific question would get you a better answer, but Rutherford's gold foil experiment proved that matter is most empty space, with very small concentrated charges within it. Most atomic models before the experiment had assumed that matter is like a "plum pudding" with subatomic particles distributed within it. Rutherford directed the experiments bombarding materials, such as gold foil, with alpha particles (postiviely charged helium nucleii), most of which simply flew right through the foil, indicating it was mostly empty space. Some particles were very strongly deflected, however, indicating concentrated strong sources of positive charge (i.e. the nucleus).
