Monatomic anions are named by adding -ide to the root of the name. Hydride, sulfide, and oxide are all examples of monatomic ions. There are several polyatomic ions. As a group, they have no specific naming rule. Hydroxide, carbonate, and dihydrogen phosphate are all examples of differently named polyatomic ions.
An ion is an atom or molecule which has lost or gained one or more valence electrons, giving it a positive or negative electrical charge.
Sodium, potassium, calcium
Anions have a negative charge. Examples are Chloride, Hydroxide, Oxide and Fluoride.
cation which is positively charged
anion which is negatively charged
Anions are negative ions; examples are Cl-, (PO4)3-, (NO3)-, F-, (SO4)2-, Br- etc.
Examples: Cl-, (CO3)-, (NO3)-, F-, Br- etc.
All the non-metals except hydrogen in some cases form anion.
Examples are F-,N3-, O2- etc.
Phosphorous and bicarbonate
Cl-
polyatomic anion
An anion is an ion with a negative charge - so SO42- is an anion
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.

Cl -As this is a negatively charged ion it is a anion.
Phosphate is a triply charged polyatomic anion.
An anion is an ion with a negative charge - so SO42- is an anion

Anion
No. An anion may contain covalent bonds, if it is a polyatomic anion, but an anion forms only ionic bonds if the anion's chemical integrity is maintained.
chloride is an anion.
ANION
anion
The anion in sulphates is the SO42-.
F is fluorine, and it is neither a cation or an anion. F^- is formed when F gains an electron. F^- is an ANION.
