Nomenclature Naming Compounds
Name positive element first with its normal name • Name negative element last & change its ending to -ide
KCl NO2 CaCl2 P2O5 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
Name Each: CaCl2 CaS K2O LiF
Deriving Formulas • Write the symbol for each element • Determine each element’s charge & apply subscripts to balance charge
Determining the Charge • Add up the oxidation numbers of all the negative elements • The positive portion must balance out the negative portion • Divide the positive portion by the metal subscript
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-mono 5-penta 2-di 6-hexa 3-tri 7-hepta 4-tetra etc
Name Each: CO S2O3N2H4 SO3
Drill: Name Each: CaO P2O5Al2S3 SO2

A group of atoms chemically combined that together have a charge
Most are oxoanions • PO4-3 SO4-2 • A root element bound to oxygen
Drill: Name each CuCl2 KBr PCl5 MgO Mn2O7 S2O3
Learn the polyatomic table on page 54 • Learn how to use the periodic table to determine polyatomic ions
Name the root element • Change the ending to -ate • PO4-3 = phosphate • Some are unusual
CN-1 OH-1 C2H3O2-1C2O4-2
Polyatomic Ion Endings • Maximum O = -ate • 1 less than max O = -ite • SO4-2 = sulfate • SO3-2 = sulfite
Follow ionic rules for naming the compound • Name the polyatomic ion as the positive or negative portion
