oksianioni
An oksianioni, also known as an oxyanion, is a polyatomic anion that contains at least one oxygen atom and has a negative charge overall. These ions are formed when oxygen atoms bond with another element, typically a non-metal, and the resulting molecule gains or loses electrons to achieve a stable electronic configuration. The negative charge arises from the presence of excess electrons.
Common examples of oksianioni include sulfate (SO₄²⁻), nitrate (NO₃⁻), carbonate (CO₃²⁻), and phosphate (PO₄³⁻). The oxidation
Oksianioni play significant roles in various chemical and biological processes. They are important components of minerals,
