What is the electron configuration of a F{eq}^-{/eq} ion?

a. {eq}1s^2 2s^2 2p^4{/eq}

b. {eq}1s^2 2s^2 2p^5{/eq}

c. {eq}1s^2 2s^2 2p^6{/eq}

d. {eq}1s^2 2s^2 2p^6 3s^1{/eq}

Electron Configuration:

The distribution of the electrons at various energy levels around the nucleus of an atom is elucidated by its electron configuration. This configuration is written in the form {eq}\rm nl^e {/eq}. Here, the energy level is {eq}\rm n {/eq} while the subshell is {eq}\rm l {/eq}. The number of electrons found in the subshell is {eq}\rm e {/eq}.
