oxide
O²⁻
An oxide is a chemical compound that contains at least one oxygen atom and one other element. Oxides can be either ionic or covalent in nature, depending on the types of bonds present between oxygen and the other element.
Some examples of ionic oxides include sodium oxide (Na2O) and calcium oxide (CaO), which are formed when metals react with oxygen. These oxides typically dissolve in water and are basic in nature, meaning they can neutralize acids.
Covalent oxides, on the other hand, are formed when nonmetals react with oxygen. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2). These oxides tend to be gases or liquids at room temperature and are typically acidic in nature.
Oxides play important roles in various industrial processes, including the production of metals, ceramics, and glass. They also play crucial roles in environmental processes such as acid rain formation and the natural carbon cycle.
