... The example in He shows that we can think that for each atom, there are electron orbitals, designated by n . Depending on the number of electrons available, one can put each electron in one of the orbitals. Each one of these orbitals for a fixed n is called a subshell, and each fixed n is called ...

BORH`S DERIVATION OF BALMER
... However, the transition from one orbit to another, the quantum jump in zero time, as a necessary condition for radiation of energy, is a drawback on Bohr’s quantum theory. So also is the failure to relate the frequency of emitted radiation to the frequency of revolution of the electron, round the po ...
