We answer questions, not explain whole breaths of work for you to turn in. Pick something in the theory you don't know and we'll try to explain it.

The internet is a great place to learn many things, but as of yet it is still a poor place to learn modern science theories. Go to a near by science library and read any book dealing with "Physical Organic Chemistry" and Huckel theory will be a chapter in it.

You have to go to a science library. Any university near you will have a science library.

alright i think i finaly am on my way

HÜCKELS RULE SAYS- Cyclic planar molules in which each of the atoms have a "p" orbit are aromatic if the contain 4n=2 pi electrons

aromatic means that it containing one or
more six-carbon rings

i think that's it... please tell me if im missing anything

That's 4n + 2  pi electrons.

"aromatic means that it containing one or
more six-carbon rings "
No, it need not be six carbon ring.  There can be various ring sizes as long as the pi electrons add to 4n+2.

Aromatic "4n +2"
Antiaromatic "4n"

Check out the article to your right titled "Annulene" I wrote it and it may be of some interest now that you know a little more about Huckel theory.
