Compounds

Ternary Compounds

• These are compounds containing three different elements. One example of a ternary compound is Sodium Phosphate or Na₃PO_{4. Under is a diagram showing the structure of Sodium Phosphate.}

• In Na₃PO_{4, sodium ion has a charged of 1+ and the phosphate ion has a charge 3-. So three sodium ions are needed to balance the charge of one ion.}
• _{Under are the common anions used for ternary compounds.}

Suffix - ate		Suffix - ite
Chlorate	- ClO3	Chlorite	- ClO2
Nitrate	- NO3	Nitrite	- NO2
Sulphate	- SO4	Sulphite	- SO3
Phosphate	- PO4	Phosphite	- PO3
Carbonate	- CO3
Silicate	- SiO3
Oxalate	- (COO)2
Acetate	- CH3COO
Aluminate	- AlO2
Zincate	- ZnO2
Plumbate	- PbO2
Chromate	- CrO4
Manganate	- MnO4

Ternary Ionic Compounds

• A ternary ionic compound is a compound composed of at least three different types of atoms usually a metal and a polyatomic ion which are bonded in ionic form.  
• In Ionic bonding, you can only bond NON-METAL and METAL. So to have a Ternary Ionic Compound, the compound should at least be composed of 3 or more non-metal and metal. 

• Above is a diagram showing the chemical structure of CaCO3.
• CaCO3 is an example of a Ternary Ionic Compound. CaCO3 has Calcium, Carbon and Oxygen. 

Ternary Covalent Compounds

• A ternary covalent compound is a compound composed of at least three or more NON-METAL and NON-METAL.
• It is similar to Ionic but there is no metal to bond with. 

• Above is a diagram showing the chemical structure of CH₃COO.
• CH₃COO is an example of ternary covalent compound because all the elements present are non-metal which are Carbon, Hydrogen and Oxygen.
