...chemical distinction between atoms is governed by the number of charges in the nucleus, which is the same as the number of electrons in its system. Hydrogen, the lightest known element, has one charge and one electron, like the earth and moon...
...ordinary mechanical laws do not account for the stability of the elements under the new theories, for they would not prevent electrons falling into the nucleus. These move in fixed orbits and new ones cannot be created. When atoms are bombarded by free electrons, the electron rebounds or transfers its energy to the atom, in which case there is an emission of light in the spectra. Sir Oliver Lodge, in his installation address as President of the Roentgen Society, London, outlined his own version of atomic theory. The nucleus he believes to be rotating at the speed of light. Surrounding...
Professor Bohr is an international authority on spectra and radio activity and has done valuable work in proving the electron theory of the composition...
Professor Bohe is an international authority on spectra and radio activity. He is believed by many to have been the originator of the electron theory of atomic composition. Professor Lyman, however, explained that this was not strictly true...
...electron theory is far older than Professor Bohe," he said, "but he did invent a model of the atom which so far has been more successful than any other in explaining certain well known facts in spectrum analysis. His model is probably the most successful and interesting to the physicist that has ever been conceived. His work has been more to establish certain facts about the electron than to prove its existence...
