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 ...

Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a ...

But instead of solving the Bohr-model problem, Hagen applied the “variational principle” – a technique usually reserved for approximating quantum-mechanical systems that cannot be solved analytically ...

The Bohr model successfully predicts hydrogen energy levels with good accuracy, but it’s a wrong in every other way. The first problem with the Bohr model is that, like the solar system, it describes ...

The atom that Bohr proposed 1 in July 1913 looked like a miniature Solar System, with electrons arranged in concentric orbits around a positively charged nucleus. In Bohr's model, electrons were ...

Bohr's atomic orbit model (Credit: S. Egts) In a way, Niels Bohr was the pioneer of quantum physics (second only to Max Planck himself). At the very least, he was one of the many fathers of the field.

The Bohr model. According to the Dane, electrons orbiting the nucleus at different distances were at different energies, and an electron inside an atom - any atom - could only have specific energies.

It's a simplistic model, yet provides insights into atoms and chemical properties, and this year marks 100 years since the model was first proposed by Danish physicist Niels Bohr.
