It appeared that if an atom attached a positive unit of electricity to itself it would be pulled in one direction through the solution by the voltage. IT APPEARED THAT IF AN ATOM ATTACHED A POSITIVE UNIT OF ELECTRICITY TO ITSELF IT WOULD BE PULLED IN ONE DIRECTION THROUGH THE SOLUTION BY THE VOLTAGE
number of atoms of a variety of different elements. In some cases, though, it liberated just half the expected number of atoms; or even, in a few cases, just a third. Scientists began to speculate that electricity, like matter, might consist of tiny units. When electricity broke up a molecule, perhaps a unit of electricity attached itself to each atom. In that case, the same quantity of electricity, containing the same number of units, would liberate the same number of atoms. In the case of some elements, each atom could attach 2 units of electricity to itself, or perhaps even 3. When that happened a given quantity of electricity would liberate only one-half, or only one-third, the usual number of atoms. (Thus, 18 units of electricity would liberate 18 atoms if distributed 1 to an atom; only 9 atoms if distributed 2 to an atom; and only 6 atoms if distributed 3 to an atom.) It was understood at the time that electricity existed in two varieties, which were called positive and negative.
