Locating Electrons and Electron Configuration

I am loving this unit so far. The less math and calculations, the better. In this lesson we learned about how to locate electrons and I understood it with ease. First you would locate the principle energy level, which is basically which row it was in going across the periodic table. Then you would find the sub-level it is in. There are four sub-levels: S,P,D, and F. After that, you simply counted the number of elements into that sub-level to locate your beloved electron. All of these components were used to make an electron configuration. For example: Oxygen has an electron configuration of 1s^2 2s^2 2p^4. The lesson was enjoyable and easy, what a blessing.
