Oxidation is the loss of electrons or gain of oxygen, while reduction is the gain of electrons or loss of oxygen.

Oxidation is the loss of electrons, while reduction is the gain of electrons.

The oxidizing agent is the substance that causes another substance to be oxidized, while the reducing agent is the substance that causes another substance to be reduced.

<p>The oxidation state of an atom is the charge it would have if the bonding electrons were assigned to the more electronegative atom. Common rules used for assigning oxidation numbers include assigning an oxidation number of 0 to free elements, -1 to oxygen in most compounds, and +1 to hydrogen in most compounds.</p> Signup and view all the answers
