Oksyanion
Oksyanion is a term used to describe an anion that contains at least one oxygen atom. These species are ubiquitous in chemistry and play a crucial role in a vast array of chemical processes and compounds. The negative charge on an oksyanion is typically delocalized across the oxygen atoms and the central atom through resonance, which contributes to their stability.
Common examples of oksyanions include sulfate (SO4^2-), nitrate (NO3^-), phosphate (PO4^3-), carbonate (CO3^2-), and permanganate (MnO4^-).
Oksyanions are fundamental components of many salts, such as sodium sulfate or potassium nitrate, which are
