It is a story of how ideas changed about the nature of the atom. These are the notes (and diagrams) I use when I teach the atomic nature of matter to non-science majors. The best thing about this ...

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 ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. By doing this, he was able ...

Bohr went on to make enormous contributions to physics and, like Rutherford, to train a new generation of physicists. But his atomic model remains the best known work of a very long career ...

Niels Bohr's new atomic model in 1913 was path-breaking for physics because it imposed new limits on the way atoms could react with each other. It was also path-breaking for the transition it ...

Bohr's atomic model 100 years old. Brilliant in its simplicity, Danish scientist's quantum leap in atomic theory has ever since provided valuable insights into chemical properties.

In 1913, Niels Bohr developed an early atom model known as the Bohr Model. ... As for his superradient atomic clock research, Bohr said there are lots of possibilities for future advancements.

Muonic helium, which has the same mass as this isotope, lasts long enough to react with a hydrogen molecule. Fleming’s team shot muons produced at the TRIUMF accelerator in Vancouver into a ...

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.

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 ...
