The answer it's actually right, " Positive particles are fired at gold foil. Most pass through, but some bounce back. "

The statement "Positive particles are fired at a gold foil. Most pass through but some bounce back" best describes Ernest Rutherford's experiment.

This is the correct answer because Rutherford used Alpha particles, which is the helium nucleus without the electrons. The alpha particles have a net positive charge of two.

In the experiment, most of the alpha particles passed through the gold foil because they did not come in close proximity with the dense positive nucleus. A lot of particles did not come in-contact with this nucleus because the atom has a very small nucleus. The few that deflected or bounced back had come in close proximity to the dense positive center of the atom.
