Dear BAba,

Electrons enter available sublevels in order of their increasing energy. A sublevel is filled or half-filled before the next sublevel is entered. For example, the ssublevel can only hold two electrons, so the 1s is filled at helium (1s2). The p sublevel can hold six electrons, the d sublevel can hold 10 electrons, and the f sublevel can hold 14 electrons. Common shorthand notation is to refer to the noble gas core, rather than write out the entire configuration. For example, the configuration of magnesium could be written [Ne]3s2, rather than writing out 1s22s22p63s2.
