All atoms are built up from a single atom, the atom of hydrogen, which consists of a positive electron or proton, the nucleus, and a single negative electron revolving around it like a satellite around the central planet. A heavier atom, say an atom of oxygen, consists of sixteen atoms of hydrogen, the positive nuclei of which form the positive nucleus or central portion of the oxygen atom. Some of the negative electrons are distributed among the positive electrons of the central nucleus, serving to cement them together, and the other negative electrons are revolving like satellites around the central nucleus. The number of these satellites is the atomic number of the atom, and it is this number, and not the atomic weight, which determines the chemical characteristics of the atoms. This is only a mere glance into the structure of Electron Physics, made here for the purpose of pointing out some of the never-dreamt-of possibilities that Electron Physics holds in view. For instance, four atoms of hydrogen combining into an atom of helium give off a certain amount of energy. We say the atoms of hydrogen degrade into the heavier atom of helium and, thereby, a certain amount of energy is liberated. A helium atom weighs less than four atoms of hydrogen, because of the diminished energy per atom of hydrogen, the decrement of the weight being proportional to the decrement of energy. This is demanded by Einstein’s theory, which is really an extension of the theory first proposed by Sir John Joseph Thomson, and it is a remarkable fact that these weight relations satisfy the prophecy of the theory. The amount of energy obtained by the degradation of the lighter into heavier atoms is enormous. But we do not know how to produce the process of this degradation. The question arises: Do not the young stars, the very hot stars, which always consist of gases of small atomic weight, obtain a supply of radiant energy from the degradation of atoms of small into atoms of high atomic weight, and, if this is so, then why shall we not some day learn this great secret from the stars? The language of the stars has many deep secrets to tell; it mystifies me just as much to-day as it did on the pasturelands of my native village fifty years ago. Many other most startling contemplations may be connected with the new views opened up by Electron Physics, all of them illustrating the beauty, the wealth, and the power of a new science which represents the marriage of two great sciences, physics and chemistry.
