No atomic model, so far as I know, has succeeded in making this difference plausible; but it is not essential to the hypothesis, that, independently of any atomic model:—(i) Three distinct ...

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.

Quantum physics just took a leap from theory to reality! Empa researchers have, for the first time, successfully built a long ...

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

Theoretical physicists, including those at the Surrey Nuclear Theory Group, are now re-examining the models used to describe atomic nuclei, as the experiments suggest that nuclear structure is far ...

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent ...

ENGLISH readers will welcome this authoritative account by Prof. Bohr of the application of his theory to atomic structure. The essay has been translated from the Zeitschrift fur Physik by L.

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 ...
