The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Atomic model. Bohr's greatest contribution to modern physics was the atomic model. The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons.

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 ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

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 ...

In Bohr’s model of the hydrogen atom, one electron, carrying a negative electrical charge, circles a nucleus consisting of a single proton, which has a positive charge.

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.

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 ...

Just as the Bohr model failed to reproduce the hydrogen atom's energy levels properly, so did the Schrödinger equation. It was quickly discovered that there were three reasons for this.

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 ...
