Question

Define oxidation - reduction in terms of electrons?

Answer 1

Surely it's reversed...

Explanation:

Oxidation is defined as the loss of electrons, while reduction is defined as the gain of electrons. Elements that are more electronegative (non-metals) are more likely to get reduced, while metals tend to be oxidized.

A mnemonic to remember is `"OILRIG"`. It stands for Oxidation is loss, reduction is gain.
