atoms are indivisible and have a dense positive nucleus.

atoms are divisible and have multiple layers of electrons scattered uniformly about the atom.

atoms are like plum pudding with positive and negative charges uniformly scattered throughout the atom.

atoms are mostly empty space with a dense positive nucleus.

the vast majority of the alpha particles went through the foil unaffected.

the vast majority of the alpha particles were deflected at 90 degrees.

one alpha particle was deflected by the gold foil.

beams of alpha particles were deflected by magnets.

are all packed inside the nucleaus of the atom

 freely move in and out of the nucleus 

revolve around the nucleus in specific orbits

 electrons do not exist, atoms only contain protons and neutrons
