ox·i·da·tion

(ŏk′sĭ-dā′shən)
1. The chemical combination of a substance with oxygen.
2. A chemical reaction in which an atom or ion loses electrons, thus undergoing an increase in valence. Removing an electron from an iron atom having a valence of +2 changes the valence to +3. Compare reduction.
Did You Know? If you've ever seen rust, you've seen oxidation. If you've ever watched a candle burn, you've seen oxidation. And if you've ever breathed, which is a good bet, you've experienced oxidation. In all these cases, oxygen is added to another substance. Rust is oxygen reacting with iron, and both burning and breathing involve oxygen reacting with carbon to free up energy stored in chemical bonds. Perhaps you have seen movies in which people are trapped in a confined space like a mine. They might light a match to see, but the burning flame uses up the same oxygen they need to survive. Rust can be thought of as burning that happens incredibly slowly. Oxygen takes electrons from whatever it is oxidizing, so chemists also use the word oxidation to describe what happens to any substance that loses electrons to another substance.

oxidation

1. A substance is oxidized if it gains oxygen, loses hydrogen, or loses electrons.
2. A chemical reaction involving loss of electrons. In the human body, oxidation occurs when breathed-in oxygen combines with molecules in food to produce energy, water, and carbon dioxide.
