Dioksidien
Dioksidien is a term that can refer to several different chemical compounds, depending on the context. Most commonly, it relates to the chemical formula XO2, where X is a nonmetal element. These are typically oxides where the nonmetal is in a higher oxidation state, bonded to two oxygen atoms. A well-known example is carbon dioxide (CO2), a gas essential for plant photosynthesis and a significant greenhouse gas. Another common example is silicon dioxide (SiO2), the primary component of sand and quartz. Sulfur dioxide (SO2) is another dioksidien, a pungent gas often produced during the combustion of fossil fuels and volcanic activity. Nitrogen dioxide (NO2) is a reddish-brown gas that contributes to air pollution and smog formation. The properties and reactivity of dioksidien vary greatly depending on the central element. Some, like carbon dioxide, are relatively stable gases at room temperature, while others, like silicon dioxide, are solid minerals.
