Analysing the experiment.
The results show the pattern you would expect for a beam of alphas.
1. Draw a circle around the areas where most of the particles are scattered,
label this circle A.
The particles that are scattered most are those starting about the ________ distance from the centre line as the ___________ of the target nucleus. This shows that the _________ of the nucleus is very ________.
4. The Thomson model of the atom was with the positive charges and mass
spread out with negative electrons like plums in the pudding. This model
means that since the mass was spread out the alpha particle would only
be deflected a small amount. Does the experiment agree with this model?
