This table orders a series of elemental metals in terms of their ability to be oxidized. Lithium (Li) is the the metal most easy to oxidize shown, while Gold (Au) is most difficult to oxidize. For reference the metals are colored by whether they are able to reduce the hydrogen atomsThe smallest particle of an element that can be involved in chemical combination with another element; an atom consists of protons and neutrons in a tiny, very dense nucleus, surrounded by electrons, which occupy most of its volume. in an acid, steam, or liquidA state of matter in which the atomic-scale particles remain close together but are able to change their positions so that the matter takes the shape of its container H2O to H2. It is most easy to reduce the hydrogen atoms on an acid, and most difficult to reduce the hydrogen atoms in liquid water.
