Answer:

The net charge of ANY ionic species is ZERO.

Explanation:

What do I mean? Rubidium sulfide is made of two ions, #Rb^+# and #S^(2-)#. But while the individual ions may be charged, oppositely charged ions will be drafted so as the charge is neutral. The sulfide ion, #S^(2-)#, thus requires #2xxRb^+# for electrical neutrality.
