Q: When something loses electrons, it must also?


Read this paragraph and choose the correct option from the provided answers:

Solution The charges, as well as the atoms, must balance in reactions. The silver atom is being oxidized from the 0 oxidation state to the 1+ state. Whenever something loses electrons, something must also gain electrons (be reduced) to balance the equation. Oxygen is a good oxidizing agent for these reactions because it can gain electrons to go from the 0 oxidation state to the 2− state.

 Choices:

- reduce protons

- slow down

- gain protons

- gain electrons


A:
gain electrons
