But there was good evidence he was right: the electrons in his model lined up with the regular patterns (spectral series) of light emitted by real hydrogen atoms. Bohr's theory that electrons ...

Bohr proposed adding to the model the new idea of quanta put forth ... His model was a huge leap forward in making theory fit the experimental evidence that other physicists had found over the ...

Standard quantum theory as developed by the likes of Niels Bohr and Werner Heisenberg in ... Two quantum field theories lie at the heart of the standard model of particle physics.

When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...

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 ...

Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

To begin with, there’s no single quantum theory. There’s quantum mechanics, the basic mathematical framework that underpins it all, which was first developed in the 1920s by Niels Bohr ...
