... If you can count separate units of a substance, you can get an exact number. For example, you can count that you have 12 pencils or 25 bottles of soda or 150 marbles. When you measure something, however, you obtain a number that is not exact. For example, you can determine that a beaker has a mass o ...

... The preceding table is vastly important. It gives you the basic 3 subatomic (smaller than an atom) particles, their respective charge, their mass, where to find them within the atom, and if the number of them can be altered. There are several subtle things to note about the table: 1. There is only ...
