Question

what are polyatomic ions ?give example?​

Answer 1

Answer:

Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.

Examples of Common Polyatomic Ions

Acetate – C2H3O2–

Bicarbonate (or hydrogen carbonate) – HCO3–

Bisulfate (or hydrogen sulfate) – HSO4–

Hypochlorite – ClO–

Chlorate – ClO3–

Chlorite – ClO2–

Cyanide – CN-

Hydroxide – OH-

Answer 2
