...billion times less dense than hydrogen, the thinnest gas known. Its particles are 4,000 times smaller than hydrogen molecules, (the smallest known). So fast are these particles moving (as shown by the tenuousness of the substance) that they go 23.5 times as fast as the fastest electron (electric particle circling an atom's nucleus) and 57% faster than light. They go, in fact...
...large as a raindrop, "they would cover the earth with a foot of water." Yet, "if we made ,one of these hydrogen atoms, which we used to think of as hard and indivisible, so large that it became a yard in diameter, nothing would yet be appreciable, because its electron would still be only a pinhead in size and its nucleus 2,000 times smaller. So while you might distinguish the orbit, its planet [electron] and sun [nucleus] would still be nearly invisible. In other words, practically all of the hydrogen atom is apparently space . ." .as empty...
...that they had made a discovery. What this was, no gossips could accurately say. All agreed, however, that it was something of vast moment-epochal, recondite, revolutionary. Some averred that these men of science had devised a terrific explosive, others that they had found a way to harness the electron. Wild fellows even declared, in a parched whisper, that they had made a synthetic...
Here is a new temptation to solve the old problem of alchemy?how to make gold. Here is the 80th electron of a mercury atom revolving around its nucleus, much like a planet around the sun, waiting to be knocked off and leave the precious old Midas-metal in the chemist's palm...
...they are attempting it. But it is not as easy as it sounds. The 80th electron cannot be displaced with a pair of tweezers or a baseball bat. For this atom, which is too small to be seen, is also too substantial to be easily dissected...
