The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks. Johannes Stark ancientcompositiongreek Change image and share on social
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 emitted by them. Johannes Stark atomicaxisbeam Change image and share on social
At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal size, or quanta, and that light is an electromagnetic wave motion. Johannes Stark composediscoverydiscrete share on social
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 several units into a selfcontained whole. Johannes Stark atomchemicaldiscovery Change image and share on social
Along a series of lines running from longer to shorter wavelengths the effect of the electric field becomes greater as the serial numbers increase - that is, as the wavelength decreases. Johannes Stark decreaseeffectelectric Change image and share on social
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 to move. Johannes Stark beamcanaldirection Change image and share on social
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 an expression of the peculiarity of their atomic structure - or, at least, of the structure of the surface.

By recognizing that the chemical atom is composed of single separable electric quanta, humanity has taken a great step forward in the investigation of the natural world. Johannes Stark atomchemicalcompose Change image and share on social
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions. Johannes Stark atomicbeginchemical Change image and share on social
