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 ...

A stylized representation of a lithium atom illustrates Niels Bohr's atomic model, that an atom is a small, positively charged nucleus surrounded by orbiting electrons. (Image credit: Boris15 ...

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 ...

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.

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.

Danish physicist Niels Henrik David Bohr made foundational contributions to understanding the atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.

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.

The name Niels Bohr may take you back to high school chemistry class, but an event tonight (June 3) promises to take people beyond textbooks, for a behind-the-scenes look at the pioneering ...
