WebbPhysicist, Ernest Rutherford was instructing two of his students, Hans Geiger and Ernest Marsden to carry out the experiment They were directing a beam of alpha particles (He 2+ ions) at a thin gold foil They expected the alpha particles to travel through the gold foil, and maybe change direction a small amount Instead, they discovered that : WebbAtoms are the building blocks of all matter They are incredibly small - for instance, about one hundred million atoms could fit side by side across your thumbnail Atoms have a tiny, dense nucleus at their centre, with electrons orbiting around the nucleus The nucleus is made up of protons and neutrons
