Report on the Rutherford Model of the Atom.

SINCE ancient times, many presents of the fraction have been developed, as the grammatical case of quite a little 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 plan in that location were inadequacies in Thomsons work. Thomson believed that atoms consisted of sm every negative charges plant in a positively charged dough, and so his model is often referred to as the plum tree Pudding Model. Rutherford began canvass the properties of matter when he performed his now well-known Scattering test of 1910. He fired of import () particles from a radioactive witness at a thin piece of paper of sublime corrupt (400 atoms thick). The alpha particle source was cover in a lead box to prevent the particles from esca ping in the defame 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 straightforward 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 hardly a(prenominal) by large amounts. His task now was to attempt to apologize these results. They did not fit Thomsons model of the atom, as in this model, there would not be a cast strong comely to deflect som! e of the alpha particles. 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.
