Chemistry 130 Nomenclature

Front 1

Monoatomic cations

Back 1

parent element + "ion"
if variable charge, parent element + (Roman Numeral charge) + "ion"

Front 2

Monoatomic anions

Back 2

Parent element + -ide + "ion"

Front 3

Polyatomic ions (not compounds!)

Back 3

1. -ate, -ite ions contain oxygen
2. -ite has one fewer O atoms than -ate
3.bi- means hydrogen
4. per- has one more O atoms than -ate
5. Hypo- has one less atom than -ite alone

Front 4

Binary compounds with fixed charge cation (neutral charge!)

Back 4

-name cation
-name anion
-use root of anion name + "-ide"

Front 5

Binary Compound with multiple charge cation

Back 5

-name cation
-multiple subscript of anion by its charge, and divide by cation subscript
-this is the cation roman numeral(charge)
-name the anion root + -ide

Front 6

Covalent Binary compounds (two non-metals)

Back 6

-use greek prefixes
-leading name does not use mono-
-name the first element plus prefix for number of atoms
-name the second element plus prefix + -ide

Front 7

Compounds with polyatomic ions (neutral charge!), naming from formula

Back 7

-do not use greek
-determine if cation is of variable charge
-if so, determine total charge of polyatomic ion by multiplying the charge of the polyatomic ion by the number of atoms present
-the cation must balance this charge, so that is the Roman Numeral for cation
-name the cation
-name the polyatomic ion

Front 8

Compounds with polyatomic ions (neutral charge!), formula from name

Back 8

-determine charge of cation
-determine charge of polyatomic ion
-use charge crossing to determine subscripts
-must used LCM subscripts

Front 9

Binary acids

Back 9

-use prefix hydro- + name root of anion and suffix -ic

Front 10

Ternary acids

Back 10

-name the polyatomic ion
-change -ate to -ic
-change -ite to -ous
-add "acid"
-include proper prefixes for polyatomic ion!
