Nomenclature Naming Compounds

Naming Binary Ionic Compounds

Name positive element first with its normal name Name negative element last & change its ending to -ide

KClCrO 2 CaCl 2 Mn 2 O 5 Al 2 O 3 H 2 S Na 2 Oetc

Name Each: FeCl 2 FeCl 3

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: CaCl 2 TiF 2 K 2 OLiF

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 Iron(III)carbide

Same rules as ionic compounds except: use geometric prefixes to determine the # of each atom

Geometric Prefixes 1-mono5-penta 2-di6-hexa 3-tri7-hepta 4-tetraetc

COS 2 O 3 N 2 H 4 SO 3 Name Each:

Write formulas for: Sodium sulfide Lead (II) iodide Diphosphorus pentoxide

Write formulas for: Chromium(III) oxide Aluminum carbide Dibromine heptoxide

Polyatomic Ion

A group of atoms chemically combined that together has a charge

Most are oxoanions PO 4 -3 SO 4 -2 A root element bound to oxygen

Naming Polyatomic Ions

Google Polyatomic Ion Chart at Home & Learn the Chart

Learn the polyatomic table on the internet Learn how to use the periodic table to determine polyatomic ions

Name the root element Change the ending to -ate PO 4 -3 = phosphate Some are unusual

CN -1 OH -1 C 2 H 3 O 2 -1 C 2 O 4 -2

H 2 O H 3 O +1 NH 3 NH 4 +1

Polyatomic Ion Endings Maximum O = -ate 1 less than max O = -ite SO 4 -2 = sulfate SO 3 -2 = sulfite

Naming Ternary Compounds

Follow ionic rules for naming the compound Name the polyatomic ion as the positive or negative portion

CaCO 3 K 2 SO 4 Name Each:

Ti(NO 3 ) 2 CaSO 3 MnSO 4 Name:

Write Formulas For: Lead (II) nitrate Aluminum sulfate Potassium chromate Ammonium phosphite

Name the Following: BaSO 4 CuNO 3 SO 2 (NH 4 ) 3 PO 4

Column 7 Dilemma for Polyatomic Ions There are 2 polyatomic names (-ate & -ite) for each root element. Polyatomic ions from column 7 have 4 possibilities

ClO 4 -1  ClO 3 -1  ClO 2 -1  ClO -1  4 examples from Column 7

ClO 4 -1  perchlorate ClO 3 -1  chlorate ClO 2 -1  chlorite ClO -1  hypochlorite 4 examples from Column 7

IO 4 -1  periodate IO 3 -1  iodate IO 2 -1  iodite IO -1  hypoiodite Also true for others
