The others before my answers are wrong. First you need to know how many electrons there are in the atom. Take for example F (fluoride). there are 9 electrons. Then you write the electron configuration. F -> 1s^2 2s^2 2p^6 3s^1 and if you count up the subscripted numbers you'll get the amount of electrons in Fluoride. Now the numbers before the letters(sub levels) are the energy levels. If you look at it, 3 is the highest occupied energy level.

Do you mean the highest electron level (or something)? The elements are arranged on the Periodic Table according to a few criteria, one being the number of each element's outer shell electrons.
