IN his letter to NATURE of January 1 on “tomic Models and X-Ray Spectra,” Dr. F. A. Lindemann deals with the approximate agreement between the recent experiments of Mr. H. G. J. Moseley on ...

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.

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's ... He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable.

His model of the atom, built upon quantum theory, fundamentally altered the way scientists viewed the atom, providing a coherent explanation for atomic stability, spectral lines, and the ...
