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 ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

Picture an atom, and you may imagine spherical electrons orbiting a nucleus packed with particles like neutrons. Only certain orbits - quantum levels - are possible. It's a simplistic model, yet ...

The Bohr atom is unquestionably a landmark in the history of physics. A century after its publication, it has inspired a remarkably diverse and ever-growing field of research. But to fully grasp the ...

A free atom is one which experiences no forces from neighbouring atoms. The Bohr model (named after Danish physicist Niels Bohr) of an atom has a small, positively charged central nucleus and ...

Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, physicists have created giant, millimeter-sized atoms that resemble it more closely than any ...

Quantum physics might not be the most approachable topic, but there’s a good chance you’ve heard of some of its elemental parts, like atoms. In the early 20th century, Danish physicist Niels Bohr ...
