What is oxidation in terms of electron transfer?
The loss of electrons by a species.
What is reduction in terms of electron transfer?
The gain of electrons by a species.
Why do oxidation and reduction occur together in many reactions?
Electrons lost by one species are gained by another.
How does the position of electrons in a half-equation distinguish oxidation from reduction?
Electrons on the product side indicate oxidation; electrons on the reactant side indicate reduction.
What can be tracked in a reaction or equation to identify oxidation and reduction?
Electron movement or changes in charge.
