In 2013, physicists used a "quantum microscope" to peer inside a hydrogen atom. Credit: A. S. Stodolna et al., 2013 ...

A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan.

As a result of quantum mechanics, ... Olszewski, Stanisław, The Bohr Model of the Hydrogen Atom Revisited, Reviews in Theoretical Science, Volume 4, Number 4, ...

Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

The first direct observation of the orbital structure of an excited hydrogen atom has been made by an international team of researchers. The observation was made using a newly developed “quantum ...

Heisenberg’s paper marked the birth of modern quantum mechanics. ... In Bohr’s model of the hydrogen atom, one electron, carrying a negative electrical charge, ...

Today, the hydrogen atom is one of the most stringent testing grounds for the rules of quantum physics, giving us a measurement of the fine structure constant — α — to better than 1-part-in ...

The model had successfully explained the spectrum of the hydrogen atom — consisting of just one proton and one electron — and the splitting of spectral lines in the presence of an applied ...

Tauonium, composed of a tauon and its antiparticle, has a Bohr radius of only 30.4 femtometers (1 femtometer = 10-15 meters), approximately 1/1,741 of the Bohr radius of a hydrogen atom.
