"Oxide" itself is the dianion (anion bearing a net charge of −2) of oxygen, an O2− ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides.

AI overview

An oxide is a chemical compound that contains at least one oxygen atom bonded with another element, with oxygen carrying a negative charge of −2 in the compound. Oxides are extremely important because they make up most of the Earth's crust, and even materials that seem like pure elements typically develop oxide coatings.

氧化物，是负价氧和另外一个化學元素組成的二元化合物，例如氧化鐵（Fe2O3）或氧化鋁（Al2O3），通常經由氧化反應產生。氧化物在地球的地殻極度普遍，而在宇宙中也是如此。氧离子（O2−）是氢氧根（OH−）离子的共轭碱，存在某些氧化物离子晶体中。自由的氧离子具强碱性（pKb ~ -22），在水溶液中是不稳定的。氧化物中的氧元素应该呈负氧化态。如果含氧二元化合物中的氧为正氧化态，例如二氟化二氧（O2F2）和二氟化氧（OF2），则它们一般称为氟化物，而非氧化物。
