Bohr's theory that electrons existed in set orbits ... to train a new generation of physicists. But his atomic model remains the best known work of a very long career.

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.

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 this book, therefore, he has attempted to provide a bridge by means of which the student of metallurgy may be led to an understanding of the general ideas on which the modern theory is based.

Students will construct structure-property models of atomic assemblies, molecules, and solids using first-principles electronic structure (such as density-functional theory), deterministic (molecular ...

For almost a century, measurements have indicated that a significant proportion of matter in the universe consists of unknown ...

Atomic, Molecular and Optical Physics (commonly referred to ... of their potential exploitation for new ways to probe and manipulate matter. Experiments and theory also tackle the fundamental chemical ...

A new model developed by scientists ... "Modeling all molecular components in atomic detail would exceed the computational power. Instead, we extended the existing theory towards smaller ...

The international team also used the data to get direct information about the deformation of the atomic nucleus in ytterbium ...
