Compound Nomenclature

Question 0

Binary Ionic Compounds

Metal/Nonmetal

Answer 0

• All end in -ide
• No prefixes
• Cation before anion (metal before nonmetal)
• Electronically neutral

Ex: sodium chloride -> NaCl
aluminum oxide -> Al2O3

Question 1

Binary Molecular Compounds

Nonmetals Only

Answer 1

-All end in -ide
-Prefixes on both elements (except mono-):
Mono-1 Di- 2
Tri- 3 Tetra- 4
Pent- 5

Ex: carbon dioxide -> CO2
diphosphorous pentoxide -> P2O3

Question 2

Transition Metal in Ionic Compounds

Answer 2

All in -ide
No prefixes
All transition metals have Roman numerals
-Roman numerals shows which ion charge of the metal that is used

Ex: copper (I) oxide -> Cu2O
copper (II) nitride -> Cu3N2

Question 3

Ternary Ionic Compounds

Polyatomic Ions

Answer 3

• Ends in -ate(oxygen)/-ide
• Metal/Nonmetal
• No prefixes
• Roman numerals for transition metals

Ex: potassium sulfate -> K2SO4
zinc hydroxide -> Zn(OH)2
ammonium chloride -> NH4Cl

Question 4

Acids

Answer 4

-Start with H (hydrogen)
Anion:
-ide -> hydro______ic acid
Ex: HCl (chlorIDE) -> hydrochloric acid

-ate -> ______ic acid
Ex: H2SO4 (sulfATE) -> sulfuric acid

-ite -> ______ous acid
Ex: HNO2 (nitrITE) -> nitrous acid

Question 5

Oxyanion

Answer 5

• ClO- -> HYPOchlorITE Hypo______ite
• ClO2- -> chlorITE ______ite
• ClO3- -> chlorATE ______ate
• ClO4- -> PERchlorATE Per______ate
