No. Throw a raisin at a plumb pudding and you will not scatter the raisin
more than a couple of degrees. Throw it at a small blob tightly packed
raisins , and you will often scatter it just a few degrees, but once in a
while scatter it at high angles. That's how Rutherford showed that the plum
pudding model of the atom was wrong, and that the atom had a nucleus.
