Flashcards for Polyatomic Compounds

Polyatomic Compounds

Groups of atoms that can be found as parts of a molecule. These atoms bond in such a way that they have a net electric charge (usually negative). The resulting group of atoms is an ion that can form an ionic bond.

Polyatomic Ion

An ion composed of two or more atoms.

Ammonium (NH4+)

A polyatomic ion consisting of one nitrogen and four hydrogen atoms.

Carbonate (CO32-)

An ion composed of one carbon atom and three oxygen atoms.

Nitrate (NO3-)

An ion composed of one nitrogen atom and three oxygen atoms.

Sulfate (SO42-)

An ion composed of one sulfur atom and four oxygen atoms.

Phosphate (PO43-)

An ion composed of one phosphorus atom and four oxygen atoms.

Acetate (C2H3O2-)

A polyatomic ion consisting of two carbon atoms, three hydrogen atoms, and two oxygen atoms.

Hydroxide (OH-)

A polyatomic ion consisting of one oxygen atom and one hydrogen atom.

Hypochlorite (ClO-)

An ion composed of one chlorine atom and one oxygen atom.

Chlorate (ClO3-)

An ion composed of one chlorine atom and three oxygen atoms.

Chlorite (ClO2-)

An ion composed of one chlorine atom and two oxygen atoms.

Oxalate (C2O42-)

An ion composed of two carbon atoms and four oxygen atoms.

Chromate (CrO42-)

An ion composed of one chromium atom and four oxygen atoms.

Perchlorate (ClO4-)

An ion composed of one chlorine atom and four oxygen atoms.

Cyanide (CN-)

An ion composed of one carbon atom and one nitrogen atom.

Permanganate (MnO4-)

An ion composed of one manganese atom and four oxygen atoms.
