Let us see about this latest theory--the Corpuscle or Electron Theory. The discovery of Radiant Matter, and the investigation of the late discovery of Radium, has led to the further discovery that each Atom, instead of being a "thing-in-itself" is a little mass containing numerous other "Things" called "Corpuscles" (or "Electrons," because electrified). The theory is this, briefly: That each Atom is a minute mass of Substance containing a number of "electrified particles," which are known as Electrons, in constant motion and vibration, revolving around each other, as do the planets, suns, and moons of the Universe--in fact each chemical Atom is like unto a Universe in itself. The simplest Atom--that which was supposed to be the "Ultimate Atom"--the Atom of Hydrogen--is supposed to contain within its tiny self no less than 1,000 minute Corpuscles, which because electrified are called "Electron," revolving in fixed and regular orbits within the containing globe of the Atom. The more complex forms of Atoms are supposed to contain a far greater number of Electrons, the authorities estimating those in an Atom of Oxygen at 10,000; those in an Atom of Gold, 100,000; and those in an Atom of Radium, 150,000. These figures are of course mere "scientific guesses" but when compared with the similar "guess" regarding the size of the Atom, they give a startling illustration of the size of the newly discovered Corpuscle or Electron. Another authority, for an illustration, asks us to consider a great globe about 100 feet in diameter--that is, of course, 100 feet through its centre. Let the globe represent the Atom. Then imagine 1,000 minute "specks," each the size of a pin-point, composed of Substance, and each containing, as in a capsule, an atom of electricity. Each "speck" is revolving around each other in a regular orbit, in that great "100 feet through" globe, and keeping well away from one another. That will give you an idea of the relative size of the Electrons and Atoms, and the room that the former have to move about in--good many feet between each, you will notice. Lots of room, and plenty to spare. Try to figure out the size of an Electron. Many readers of the magazines have been confused as to the relation between the Corpuscles and the Electrons (or Ions, as some have called the latter.) The matter is very simple. They are both the same. The Corpuscle is the tiny particle of Matter, which because it is electrified and has thus become the "unit of electricity," is called an "Electron." From the viewpoint of Substance we call the tiny particle a "Corpuscle"--from the viewpoint of Electricity, we call it an "Electron."
