Oxide
An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of -2. Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the oxygen in air or in water . Hydrocarbon combustion affords the two principal carbon oxides: carbon monoxide and carbon dioxide. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al2O3 that protects the foil from further corrosion.

Oxide
Ein Oxid (von griech. ὀξύς, oxýs = scharf, spitz, sauer) ist eine Sauerstoff-Verbindung, in der dieser die Oxidationszahl −II hat. Die meisten Oxide entstehen, wenn brennbare Stoffe mit Sauerstoff reagieren (Ursprung des Wortes Oxidation): Bei ihrer Oxidation geben sie Elektronen an das Oxidationsmittel Sauerstoff ab, so dass Oxide gebildet werden.

Oxider
Oxider är kemiska föreningar mellan syre och ett eller flera andra grundämnen, exempelvis rost (= järnoxid), eller bauxit (=aluminiumoxid). Olika typer av oxider förekommer rikligt i jordskorpan och är även vanliga beståndsdelar i fast materia över huvud taget i universum.
