An element M reacts with another element X to form $MX^{2}$ . In terms of loss or gain of electron, identify the element oxidized and reduced. I need help in understanding this question, I know what a redox reaction is in terms of loss or gain of electron. However, I am not able to solve this question. I think that's maybe because the oxidation state or valency is not given for the unknown elements. Like, how do I know if the element is gaining or loosing electron when I don't know it's valency.

I repeat, I need to UNDERSTAND this question, I already know the answer but am just confused about how to solve it...

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
