of calculating valency-and (generally) Bohr's theory of the atoms more complex than hydrogen and helium-or give up van den Broek's hypothesis, that the charge of the nucleus of Rutherford's atom is equal to the atomic number (which hypothesis was accepted by Bohr as one of his ...
Between 1909 and 1911, Ernest Rutherford, a Cambridge physicist, and his associates Hans Geiger and Ernest Marsden performed experiments that provided strong evidence concerning the internal structure of an atom. They took a very thin metal foil, such as gold or platinum, and aimed a beam of ...

TO give a comprehensive critical survey of the prevailing theories of atomic structure and to indicate their triumphs and inadequacies in a volume of reasonable size is the professed object of the book under review. This is a bold design. It is all the greater pleasure therefore to record that...
