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 began to work on the problem of the atom's structure. Ernest Rutherford had recently suggested the atom had a miniature, dense nucleus surrounded by a cloud of nearly weightless electrons.

The quantum fix. Famed Danish physicist Niels Bohr was the first person to propose a solution to this issue. In 1913, he suggested that electrons in an atom couldn't just have any orbit they wanted.

Bohr offered the first successful theoretical model of the atom in 1913, suggesting that electrons traveled in orbits around the atom's nucleus like planets orbiting a star.

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

In the years that followed, the atom-with-nucleus served as the backdrop for the formulation of quantum mechanics, and Bohr much later went on to explain how the nucleus behaved like a drop of ...

As part of his contributions, Bohr developed the ‘Bohr Model’ of the atom, in which he proposed that the electron was able to occupy only certain orbits around the atomic nucleus.

In the case of his atom, when the electrons got far away from the nucleus. Bohr's model of the atom was incomplete and would later be replaced by the valence shell model that remains to this day.

Niels Bohr 1885 - 1962. Niels Bohr was born and educated in Copenhagen, Denmark. ... That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus. If the atom ...
