A. Experiments showed that the atom is made of smaller particles. Reason being: neutrons don't orbit the nucleus, the atom is not invisible, and alpha particles are larger than hydrogen atoms, which cancels out the possibility of atoms consisting of them (you can't be made of something larger than yourself).
