2, and is remarkable in having direct chemical bonds between two notoriously unreactive atoms, xenon and gold, with xenon acting as a transition metal ligand. The compound Xe 2 Sb 2 F 11 contains a Xe–Xe bond, the longest element-element bond known (308.71 pm = 3.0871 Å). The most common oxide of xenon (XeO 3) is strongly acidic.
An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
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.

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 (only simple oxides, oxyhalides, and related compounds, not hydroxides, carbonates, acids, or other compounds listed elsewhere)
Superoxides are a class of compounds that are very similar to peroxides, but with just one unpaired electron for each pair of oxygen atoms (O − 2). [6] These compounds form by oxidation of alkali metals with larger ionic radii (K, Rb, Cs). For example, potassium superoxide (KO 2) is an orange-yellow solid formed when potassium reacts with oxygen.
Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
