The oxide ion is a single oxygen atom that has been ionized. By looking at its place in the periodic table, you can see that its normal ionization is So the chemical formula for oxide is O2- K views. Aug 05, The formula for an oxide ion is O2-, which shows that it is an anion. An oxide is a compound formed by the combination of oxygen and another element. Oxygen can form many different oxide compounds with both metals and nonmetals. Metal oxides can be compounds that contain alkali metals, alkaline earth metals and transition victorsfc.comted Reading Time: 30 secs. What is the correct formula for the oxide ion? An oxide ion is a negatively charged oxygen atom. This means it has gained two electrons from another atom. Thus, it is represented as O2- (2- is super scripted).

Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the oxygen in air or in water. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al 2 O 3 called a passivation layer that protects the foil from further corrosion.

Examples are carbon , iron , nitrogen see nitrogen oxide , silicon , titanium , and aluminium. In such cases the oxides are distinguished by specifying the numbers of atoms involved, as in carbon monoxide and carbon dioxide , or by specifying the element's oxidation number , as in iron II oxide and iron III oxide. Due to its electronegativity , oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. Noble metals such as gold or platinum are prized because they resist direct chemical combination with oxygen, and substances like gold III oxide must be generated by indirect routes.

Two independent pathways for corrosion of elements are hydrolysis and oxidation by oxygen. The combination of water and oxygen is even more corrosive. Virtually all elements burn in an atmosphere of oxygen or an oxygen-rich environment. In the presence of water and oxygen or simply air , some elements sodium react rapidly, to give the hydroxides. In part, for this reason, alkali and alkaline earth metals are not found in nature in their metallic, i.

Cesium is so reactive with oxygen that it is used as a getter in vacuum tubes , and solutions of potassium and sodium, so-called NaK are used to deoxygenate and dehydrate some organic solvents. The surface of most metals consists of oxides and hydroxides in the presence of air. A well-known example is aluminium foil , which is coated with a thin film of aluminium oxide that passivates the metal, slowing further corrosion.

The aluminum oxide layer can be built to greater thickness by the process of electrolytic anodizing. Though solid magnesium and aluminum react slowly with oxygen at STP they, like most metals, burn in air, generating very high temperatures.

Finely grained powders of most metals can be dangerously explosive in air. Consequently, they are often used in solid-fuel rockets. Free oxygen production by photosynthetic bacteria some 3. Oxides have a range of different structures, from individual molecules to polymeric and crystalline structures.

At standard conditions, oxides may range from solids to gases. Oxides of most metals adopt polymeric structures. Because the M-O bonds are typically strong and these compounds are crosslinked polymers , the solids tend to be insoluble in solvents, though they are attacked by acids and bases. The formulas are often deceptively simple where many are nonstoichiometric compounds. Carbon dioxide is the main product of fossil fuel combustion.

Carbon monoxide is the product of the incomplete combustion of carbon-based fuels and a precursor to many useful chemicals. Sulfur dioxide , the principal oxide of sulfur , is emitted from volcanoes. Nitrous oxide "laughing gas" is a potent greenhouse gas produced by soil bacteria.

Although most metal oxides are polymeric , some oxides are molecules. Examples of molecular oxides are carbon dioxide and carbon monoxide. All simple oxides of nitrogen are molecular, e. Phosphorus pentoxide is a more complex molecular oxide with a deceptive name, the real formula being P 4 O Some polymeric oxides depolymerize when heated to give molecules, examples being selenium dioxide and sulfur trioxide.

Tetroxides are rare. The more common examples: ruthenium tetroxide , osmium tetroxide , and xenon tetroxide. Many oxyanions are known, such as polyphosphates and polyoxometalates. Of course many compounds are known with both oxides and other groups. In organic chemistry , these include ketones and many related carbonyl compounds. For the transition metals, many oxo complexes are known as well as oxyhalides. Conversion of a metal oxide to the metal is called reduction.

The reduction can be induced by many reagents. Many metal oxides convert to metals simply by heating. Metals are "won" from their oxides by chemical reduction, i. A common and cheap reducing agent is carbon in the form of coke. The most prominent example is that of iron ore smelting.

Many reactions are involved, but the simplified equation is usually shown as: [2]. Metal oxides can be reduced by organic compounds. This redox process is the basis for many important transformations in chemistry, such as the detoxification of drugs by the P enzymes and the production of ethylene oxide , which is converted to antifreeze. In such systems, the metal center transfers an oxide ligand to the organic compound followed by regeneration of the metal oxide, often by oxygen in the air. Metals that are lower in the reactivity series can be reduced by heating alone.

Metals that are more reactive displace the oxide of the metals that are less reactive. For example, zinc is more reactive than copper , so it displaces copper II oxide to form zinc oxide :. Apart from metals, hydrogen can also displace metal oxides to form hydrogen oxide , also known as water:. Since metals that are reactive form oxides that are stable, some metal oxides must be electrolyzed to be reduced. This includes sodium oxide , potassium oxide , calcium oxide , magnesium oxide , and aluminium oxide.

The oxides must be molten before immersing graphite electrodes in them:. Oxides typically react with acids or bases , sometimes both. Those reacting only with acids are labeled basic oxides. Those reacting only by bases are called "acidic oxides". Oxides that react with both are amphoteric. Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals metalloids.

This reactivity is the basis of many practical processes, such as the extraction of some metals from their ores in the process called hydrometallurgy. Oxides of more electropositive elements tend to be basic. They are called basic anhydrides. Exposed to water, they may form basic hydroxides.

For example, sodium oxide is basicwhen hydrated, it forms sodium hydroxide. Oxides of more electronegative elements tend to be acidic. They are called "acid anhydrides"; adding water, they form oxoacids. For example, dichlorine heptoxide is an acid anhydride; perchloric acid is its fully hydrated form. Some oxides can act as both acid and base. They are amphoteric. An example is aluminium oxide. Some oxides do not show behavior as either acid or base.

In the 18th century, oxides were named calxes or calces after the calcination process used to produce oxides. Calx was later replaced by oxyd. The reductive dissolution of a transition metal oxide occurs when dissolution is coupled to a redox event. Reductive dissolution does not necessarily occur at the site where the reductant adsorbs. Instead, the added electron travel through the particle, causing reductive dissolution elsewhere on the particle.

Sometimes, metal-oxygen ratios are used to name oxides. Thus, NbO would be called niobium monoxide and TiO 2 is titanium dioxide. This naming follows the Greek numerical prefixes. In the older literature and continuing in industry, oxides are named by adding the suffix -a to the element's name. In such species, oxygen is assigned higher oxidation states than oxide. The chemical formulas of the oxides of the chemical elements in their highest oxidation state are predictable and are derived from the number of valence electrons for that element.

Even the chemical formula of O 4 , tetraoxygen , is predictable as a group 16 element. One exception is copper , for which the highest oxidation state oxide is copper II oxide and not copper I oxide. Another exception is fluoride , which does not exist as one might expectas F 2 O 7 but as OF 2.

Since fluorine is more electronegative than oxygen, oxygen difluoride OF 2 does not represent an oxide of fluorine, but instead represents a fluoride of oxygen. The following table gives examples of commonly encountered oxides. Only a few representatives are given, as the number of polyatomic ions encountered in practice is very large.
