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..
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 th….
A beam of luminous hydrogen canal rays has, owing to its velocity, exactly the same direction as that of the electric field in which it may be made t….
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to e….
Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does t….
The discovery of various phenomena has led to a recognition of the fact that the chemical atom is an individual which again is itself made up of seve….
Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - ….
The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle..
By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the ….
The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks..
We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and eve….
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….
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 th….
The most common and most important result of them is that the nature and size of the effect on corresponding series of different elements are largely….
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 l….
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….
By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation o….
We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines em….
The emitters of the spectral series are without exception single atoms, not compounds of atoms..
For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectr….
At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal si….
