For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.

In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a spectral line appeared to me to be the result of the coherence and co-operation of several electric quanta. Johannes Stark appearatomcoherence share on social
The emitters of the spectral series are without exception single atoms, not compounds of atoms. Johannes Stark atomcompoundemitter Change image and share on social
Many scientists will have to contribute to the solution of the great problem; they will have to follow up and measure all those phenomena in which the atomic structure is directly expressed. Johannes Stark atomiccontributedirectly Change image and share on social
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms. Johannes Stark atomchangechemical share on social
Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist. Johannes Stark abundanceatomchemical share on social
An external electric field, meeting it and passing through it, affects the negative as much as the positive quanta of the atom, and pushes the former to one side, and the latter in the other direction. Johannes Stark affectatomdirection share on social
The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer. Johannes Stark atomchangeelectron Change image and share on social
It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we do our solar system. Johannes Stark atomcenturychemical Change image and share on social
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom.
