Verified step by step guidance

Identify the correct charge and name for the sodium ion. Sodium typically loses one electron to form a cation with a +1 charge, so its ion is written as $\mathrm{Na^{+}}$ and called the sodium ion.

Identify the correct charge and name for the chloride ion. Chlorine typically gains one electron to form an anion with a -1 charge, so its ion is written as $\mathrm{Cl^{-}}$ and called the chloride ion.

Check each option to see if the ion symbols and names match the common charges and names for sodium and chloride ions.

Eliminate options where the charges do not correspond to the typical ionic charges of sodium (+1) and chloride (-1), or where the names do not match the ion symbols.

Conclude that the correct pairing is $\mathrm{Na^{+}}$: sodium ion and $\mathrm{Cl^{-}}$: chloride ion, because both the charges and names are correctly matched.
