For example, Cu compounds with Cu oxidation state +2 are called cupric and those with state +1 are cuprous. [4]: 172 The oxidation numbers of elements allow predictions of chemical formula and reactions, especially oxidation-reduction reactions. The oxidation numbers of the most stable chemical compounds follow trends in the periodic table.
Oxides, such as iron oxide or rust, Fe 2 O 3, form when oxygen combines with other elements. Due to its electronegativity, oxygen forms chemical bonds with almost all other free elements at elevated temperatures to give corresponding oxides. However, some elements, such as iron which oxidises to iron oxide, or rust, Fe 2 O
Iron(III) oxide – Fe 2 O 3; Lanthanum(III) oxide – La 2 O 3; Lead(II) oxide – PbO; Lead dioxide – PbO 2; Lithium oxide – Li 2 O; Magnesium oxide – MgO; Potassium oxide – K 2 O; Rubidium oxide – Rb 2 O; Sodium oxide – Na 2 O; Strontium oxide – SrO; Tellurium dioxide – TeO 2; Uranium(IV) oxide – UO 2
For example, the basic oxide Li 2 O becomes the hydroxide LiOH, and BaO becomes Ba(OH) 2 after reacting with water. In contrast, non-metals usually form acidic oxides . In general, the basicity of oxides increases when towards the lower-left corner of the periodic table , which corresponds to increased metallic properties.

In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [ 1 ] [ 2 ] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide ( CO 2 ).
