Question

f-express your answer in complete form, in order of increasing orbital. for example, $1s^{2}2s^{2}$ would be entered as 1s^22s^2.

Explanation:

Step1: Determine the atomic number of F

The atomic number of F (fluorine) is 9.

Step2: Write the electron configuration of F atom

The electron configuration of F atom is \(1s^{2}2s^{2}2p^{5}\).

Step3: Consider the gain of one electron for \(F^{-}\)

\(F^{-}\) has one more electron than F atom. So the electron configuration of \(F^{-}\) is \(1s^{2}2s^{2}2p^{6}\).

Answer:

1s^22s^22p^6
