Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are… — Johannes Stark Copy Share Image
We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis… — Johannes Stark Copy Share Image
By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to… — Johannes Stark Copy Share Image
For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and… — Johannes Stark Copy Share Image
The emitters of the spectral series are without exception single atoms, not compounds of atoms. — Johannes Stark Copy Share Image
The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself… — Johannes Stark Copy Share Image
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change… — Johannes Stark Copy Share Image
The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural… — Johannes Stark Copy Share Image
It is more likely that more than a century will pass before we know the structure of the chemical atoms as thoroughly as we… — Johannes Stark Copy Share Image
Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality… — Johannes Stark Copy Share Image
The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks. — Johannes Stark Copy Share Image
At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal… — Johannes Stark Copy Share Image
Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase… — Johannes Stark Copy Share Image
In my view the structure of the whole atom was that of an individual, with all its parts interconnected, and the emission of a… — Johannes Stark Copy Share Image
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to… — Johannes Stark Copy Share Image
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive… — Johannes Stark Copy Share Image
A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which… — Johannes Stark Copy Share Image
We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second… — Johannes Stark Copy Share Image
