positive negative atoms
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.
discovery light facts
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.
atoms done may
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.
greek mind ancient
The question of the composition of perceptible objects is one which already occupied the mind of the ancient Greeks.
atoms compounds exception
The emitters of the spectral series are without exception single atoms, not compounds of atoms.
individuality doe different
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.
