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 ...

Bohr’s Model of an Atom: Danish Physicist Niels Bohr received his Ph.D. from the University of Copenhagen in 1911. In 1922, he was awarded the Nobel Prize in Physics for his work on the atom’s ...

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 proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus.

In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

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 much ...

and this year marks 100 years since the model was first proposed by Danish physicist Niels Bohr. The idea that matter comprises indivisible units dates back to Indian and Greek philosophers.

One hundred years after Niels Bohr published his model of the atom, a special issue of Nature explores its legacy — and how much there is still to learn about atomic structure. July 1913 saw ...

One hundred years ago, Niels Bohr developed the Bohr model of the atom, where electrons go around a nucleus at the centre like planets in the Solar System. The model and its implications brought a ...
