-2
The resulting oxygen ion has a charge of -2.
Sulfur gains 2 electrons to become stable.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Under the usual chemical conditions oxygen gains 2 electrons to form ions. However when ionized by electrical discharges or other high energy physical processes oxygen can lose any number of electrons to form ions (even all of its electrons).
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
-2
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
The resulting oxygen ion has a charge of -2.

All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions. Gaining electrons- If atoms gain electrons then they are getting negatively charged particles making them have a negative charge. Losing electrons- If atoms lose electrons then they are losing a negative charge and they become a positively charged ion. Oxygen- Oxygen will have a negative charge before a positive charge because it needs only two electrons to have a stable valence level. For example, Oxygen will take the electrons from two Hydrogen atoms and make H20.

The chemical formula for magnesium oxide is MgO. Magnesium has valency +2 and oxygen has -2. So, magnesium donates two electrons and oxygen gains two electrons to form ionic bond.The chemical formula for strontium oxide is SrO. Strontium has valency +2 and oxygen has -2. So, strontium donates two electrons and oxygen gains two electrons to form ionic bond.
Gains two electrons. S 2-.
Magnesium is 2+ Oxygen is 2- Mg2O2 should really be written out MgO since the two's cancel out. Mg is a metal so it loses 2 electrons to become a noble gas which makes it a positive 2 Oxygen is a non-metal which means it gains 2 electrons making is a negative 2
