  ........................The Atom..................{part one} Most of us are familiar with the fact that any matter whether a liquid, or a solid, or a gas, is made up f molecules. A molecule is the smallest particle that a compound can be reduced to before it breaks down into its element. For example, if we took a grain of table salt and kept breaking it in half until it got as small as it possibly could and yet still be salt, we would have a molecule of salt. If we then broke it in half again, the salt would change into its elements. 1-a grain of salt 2-can be reduced to 3-a molecule of salt {sodium chlorine: . . } by urlLink mohammadreza_naserian
