Where does f go in electron configuration?

Fluorine is the ninth element with a total of 9 electrons. In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for F go in the 2s orbital. The remaining five electrons will go in the 2p orbital.
