In examining atomic structure though, we have to clarify this statement. An atom cannot be broken down further without changing the chemical nature of the substance. For example, if you have 1 ton, 1 gram or 1 atom of oxygen, all of these units have the same properties.

Avogadro's number and the mole are very important to the understanding of atomic structure. The Mole is like a dozen. You can have a dozen guitars, a dozen roosters, or a dozen rocks. If you have 12 of anything then you would have what we call a dozen.

There are different models of the structure of the atom. One of the first models was created by Niels Bohr, a Danish physicist. ... Using one of the first important equations in atomic structure (developed by Niels Bohr), we can calculate the amount of energy in an atom with an electron at some value of n:

I'll show you some of the details of atomic structure using an interactive periodic table applet, which, I hope, should now have opened in another window. ... Now that we've talked about the structure of atoms, can you answer my question about their sizes?
