Answer:

Well, you have a series of binary PAIRS of ions here....and so I think it is #"option 4"#

Explanation:

And so we gots #Na^+Cl^-#, i.e. 10 electrons associated with the #Na^+# cation, and 18 electrons associated with the #Cl^+# anion.

And for #Li^+F^-#, i.e. 2 electrons associated with the #Li^+# cation, and 10 electrons associated with the #Cl^-# anion.

And for #K^+Br^-#, i.e. 18 electrons associated with the #K^+# cation, and 36 electrons associated with the #Br^-# anion.

And for #Rb^+Br^-#, i.e. 36 electrons associated with the #Rb^+# cation, and 36 electrons associated with the #Br^-# anion.
