Answer:
Oxygen Ion: -1 charge
Sulfur Ion: Neutral charge
Explanation:
Protons always have a + charge.
Electrons always have a - charge.
Oxygen:
If we have 8 protons and 9 electrons, we can see that we would only have +8 charge vs a -9 charge. Therefore:
8 - 9 = -1 charge overall
Sulfur:
If we have 16 protons and 17 electrons, we can see that we would have an overall charge of -1:
16 - 17 = -1 charge overall
However, since we lost an electron, we now only have 16 electrons:
16 - 16 = 0 charge, or neutral overall
