(C) To determine the electronic configuration,we count the total number of electrons in each species:$1$. $F^{+}$: Atomic number $9$,so $9 - 1 = 8$ electrons.$Ne$: Atomic number $10$,so $10$ electrons.$2$. $Li^{+}$: Atomic number $3$,so $3 - 1 = 2$ electrons.$He^{-}$: Atomic number $2$,so $2 + 1 = 3$ electrons.$3$. $Cl^{-}$: Atomic number $17$,so $17 + 1 = 18$ electrons.$Ar$: Atomic number $18$,so $18$ electrons.$4$. $Na$: Atomic number $11$,so $11$ electrons.$K$: Atomic number $19$,so $19$ electrons.Since $Cl^{-}$ and $Ar$ both have $18$ electrons,they have the same electronic configuration.

Which of the following pairs of atoms or ions have the same electronic configuration?
