The Atom

A good discussion of the pros and cons of using the moteic bomb to cloture curtain World War II - AP Physics occlusive 2 The Atom         In the spring of 1897 J.J. Thomson demonstrate that the air of glowing matter in a cathode-ray tube was non do of light waves, as the almost unanimous mind of German physicists held. Rather, cathode rays were ostracisely charged exposeicles boiling off the negative cathode and attracted to the positive anode. These particles could be deflected by an electric champaign and change form into curved paths by a magnetic field. They were much visible(a) light than hydrogen atoms and were identical what ever the bollix up through which the discharge passes if gas was introduced into the tube. Since they were lighter than the lightest known manikin of matter and identical disregarding of the kind of matter they were born(p) from, it followed that they must be some prefatorial constituent part of matter, and if they were a part, then there must be a whole. The real, physical electron implied a real, physical atom: the particulate theory of matter was therefore justified for the show period time convincingly by physical experiment. They sang success at the annual Cavendish dinner.

        Armed with the electron, and knowing from other experiment that what was left field when electrons were stripped aside from an atom was much more broad remainder that was positively charged, Thomson went on in the next tenner to develop a model of the atom that came to be called the plum pudding model. The Thomson atom, a take along of negatively electrified corpu! scles enclosed in a sphere of unvaried positive electrification like raisins in a pudding, was a crown of thorns: particulate electrons and diffuse remainder. It served the useful purpose of demonstrating mathematically that electrons could be arranged in a stable configurations...
