Naming Binary Ionic Compounds

•Name positive element first with its normal name

•Name negative element last & change its ending to -ide

KCl CrO2

CaCl2 Mn2O5

Al2O3 H2S

Na2O etc

Name Each:

FeCl2

FeCl3

If the Positive element is not from columns I or II

•its ox # must be determined and written in roman numerals

Determining the Charge

1) Add up the oxidation numbers of all the negative elements

2) The positive portion must balance out the negative portion

3) Divide the positive portion by the metal subscript

Name Each:

CaCl2 TiF2

K2O LiF

Deriving Formulas• Write the symbol for each

element

• Determine each element’s charge & apply subscripts to balance charge

Derive Formulas•Magnesium chloride

•Lead(II)sulfide
