THE beautiful conception which inspires and co-ordinates practically the whole of modern atomic physics is the atomic model of Rutherford and Bohr. Its essential feature-the nucleus-was first put ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons ... However, there was still a difference between the atomic number of the atom and the atomic mass.

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 ...

This "Rutherford model" would form the basis of modern atomic physics and paved the way for the quantum theory later developed by Niels Bohr. In 1917, Rutherford made another monumental ...
