In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific ... difference between the atomic number of the ...

Quantum physics began in 1900 when the German physicist Max Planck determined the scale of quantum phenomena. In 1905, Albert ...

Different types of atoms have different energy levels. As a result each produces photons with different energy and so the line spectra for different elements will be different. This means that ...
