SINCE ancient times, many works of the hint have been developed, as the airfield of bulk attempting to account for properties of matter they had observed. The model developed by Lord Ernest Rutherford introduced many new ideas about the atom, and even though it is at one time quite old, many people still adjoin the atom in the way he did. Rutherford was a actor student of J.J. Thomson, but he thought process there were inadequacies in Thomsons work. Thomson believed that atoms consisted of sm every negative charges infix in a positively charged dough, and so his model is often referred to as the plum tree Pudding Model. Rutherford began analyse the properties of matter when he performed his now well-known Scattering experiment of 1910. He fired of import () particles from a radioactive kickoff at a thin piece of paper of sybaritic frustrate (400 atoms thick). The alpha particle source was cover in a lead box to prevent the particles from escaping in the wro ng(p) direction: only those that passed by dint of the opening towards the gold foil were allowed to escape. Fluorescent screens were used as detectors, and the impact of the alpha particles showed up on them. The results of the experiment were unexpected, but exciting.
Almost all of the particles passed sequent through the gold foil as if it was non there, and were detected on the other side. Some were deflected by atomic amounts, and very few by large amounts. His task now was to attempt to inform these results. They did not fit Thomsons model of the atom, as in this model, there would not be a cast stro ng rich to deflect some of the alpha partic! les. So Rutherford suggested that most of the atom consisted of empty space. This explained why the majority of particles had passed through the foil unaffected.
