Solution

Electronic configuration:
“The distribution of electrons into orbitals of an atom is called its electronic configuration”.
The general notation of electronic configuration is $s^{a} p^{b} d^{c}$ where $s, p,$ and $d$ represents the subshell and $a, b$ and $c$ represents the number of electrons present in the subshell as superscript.
Atomic number:
The symbol of Fluorine is $F$ .
Atomic number of Fluorine is $9$ and it is a part of halogen family.
As the atomic number is equal to the number of electrons present in a neutral element. So, the number of electrons is $9$ .
The electronic configuration of Fluorine is $1 s^{2} 2 s^{2} 2 p^{5}$ .
