yeah,,,Its a relatively easy question,,but most of the chemists don't know why...so why does an electron know where to go..even students have a hard time telling 1s1,2s2 2p6 etc...

can the neutroni...guy tell me exactly wat he is saying?..does he actually get wat I mean..or i don't get wat he means...and for the second answer..how does the electron know it is their limit?

actually some of you have unconciously answered my question

The Aufbau Principle states that electrons want to enter the lowest energy level first. This is because a smaller energy content leads to a more stable situation for the electron. This lowest energy state is the most stable all other matter as well.
By looking at a chart like the one linked in the sources below, one can how the orbitals rank in terms of energy content.
This, of course, is not necessarily where the electron will be. That will depend on if the electron has been excited by electricity or heat or any other form of energy that may change its position from this ground state.

This is completely due to the energy the electron has. When in the ground state, or "unexcited" state, the elctrons are closest into the nucleus of the atom. You can't fit more than a certain number into the same "shell" because of the Pauli Exclusion Principle. I could bore you with more detailed Quantum Mechanical details, but that is the essence.
Think of it this way: electrons don't "know" anything, they are just being "territorial" and won't let other electrons "crowd" them.

Electrons are negatively charged and thus repel each other and would like to be as far as possible from each other.Electrons fill up starting from the lowest energy orbital and increasingly build up.The s,p,d,f structure is probably the way to maximize the space between electrons.

the last electron/valence electron will be situated next to the octet formed part(one of the noble gases)?
example...
chlorine: (He) 2s2 2p5
??? hahaha... cant explain it

actually they don't know where to go all they know that their limit is surrounding the nucleus and that is their limit so they stick to that.

think you're smart. think again.. ponder over the relativity theory.
