During the alpha particle scattering experiment, why were some particles deflected at angles as they travelled through?

• Most of the atom is empty space meaning it was difficult for particles to maintain a straight path.

• The mass of the atom is concentrated in the nucleus, which has a tiny volume.

• Alpha particles were repelled by a concentration of positive charge in the centre of the atom.

• They were attracted to electrons surrounding the nucleus, taking them off course.
