Answer:-
.
Explanation:- Atomic number for fluorine(F) is 9 and it's electron configuration is
.
is formed when F loses one electron from it's valence shell.

Second shell is the valence shell for fluorine and so it loses one electron from 2p to form
and the electron configuration of the ion becomes
.
The "sub shells" are the orientations and shapes for your orbitals, going in order by Shells are a collection of subshells with the same principle quantum number, and subshells are a collection of orbitals with the same principle quantum number and angular momentum quantum number. Hope this helps :)
