First Step in NamingFirst Step in Naming
• Find metal
• If metal has only one oxidation state it’s easy
• If metal has more than one oxidation state, there’s an extra step

Naming Binary Ionic Compounds
1. Always name metal (+ ion) first
2. Write stemstem nonmetal (- ion)
3. Add ending “ide” to nonmetal

• Hydrogen = hydr• Nitrogen = nitr• Oxygen = ox• Fluorine = fluor• Chlorine = chlor• Bromide = brom• Iodide = iod• Phosphorus = phosph• Sulfur = sulf• Tellurium = tellur• Sellenium = selen• Arsenic = arsen

Metals with > 1 oxidation state
• Use formula to figure out oxidation Use formula to figure out oxidation state metal state metal
• Ex: Fe can be Fe+2 oror Fe+3
• Name FeO and Fe2O3
– 2 different2 different compounds – cannot name both iron oxide – every formula has 1 name only

FeO and Fe2O3
• Compounds are electrically neutral
• Oxygen is -2
FeOFeO
Name: Name: Iron (II) oxideIron (II) oxide(II = 2 for (II = 2 for ++2 charge on Fe)2 charge on Fe)
1 O (-2)1 O (-2)
so Fe must be +2so Fe must be +2

FeO and Fe2O3
FeFe22OO33
O is -2O is -2
3 O’s 3 O’s [3 x (-2) = -6][3 x (-2) = -6]total negative chargetotal negative charge
Total positive Total positive charge must be +6charge must be +6
So each Fe is +3So each Fe is +3Iron (III) oxideIron (III) oxide

Summary for Binary Ionic Summary for Binary Ionic CompoundsCompounds
• Formula: positive first, always
• metal > 1 oxidation state, name needs roman numeral
• Name = metal + stem nonmetal + ide
