1 - Naming Binary Ionic CompoundsIonic compounds are made of cations stuck to anions in a 3 dimensional crystal structure called a lattice.
Binary ionic compounds are made of two different elements (“bi” means “two”)
Example:
Sodium Chloride
The “ionic bond” is the attractive force between the positive cation and the negative anion.
Recall: 1) A cation’s name is the same as the name of the element.
sodium sodiumcalcium calcium
2) An anion’s name takes the ending “ide”
chlorine chloridefluorine fluoride
A few anions can sometimes be confusing. For example:
Does oxygen become (a) oxygide or (b) oxide ?
Does nitrogen become (a) nitrogide or (b) nitride ?
Does phosphorus be come(a) phosphoride or (b) phosphide ?

Note: Only the valence electrons are shownA sodium chloride lattice
Sodium ion, Na+
Chloride ion, Cl
Hopefully the terms “oxide”, “nitride” and “phosphide” sounded correct to you.
If they didn’t just “sound right” then you’ll need to memorize these ion names.
Now for some practice!

2 - Naming Binary Covalent Compounds
Recall: Covalent bonds form when elements ______________________ electrons.
Between what types of elements do covalent bonds form?
_______________________ and __________________________
When elements bond covalently they mostly form __________________________
(little clusters of atoms bonded covalently)
Very rarely they will form giant _____________________________________________
in which every atom is covalently bonded to the atoms around it.

nitrogen monoxide
New: Naming binary covalent compounds is much like naming binary ionic
compounds with one important difference
Stuff that is the same
When we name the first element listed in the compound, do NOT change the ending (no “ide”)
ex. IONIC CaF2 = calcium fluoride
ex. IONIC CuF2 = copper (II) fluoride
ex. COVALENT CO2 = carbon dioxide
ex. COVALENT P2F6 = diphosphorus hexafluoride
When we name the second element listed in the compound we DO change the ending to “ide” (like an anion…although it is not an anion!)
ex. IONIC K3N = potassium nitride
ex. IONIC FeO = iron (II) ox i de
ex. COVALENT PCl3 = phosphorus trichloride
ex. COVALENT N2O4 = dinitrogen tetroxide
Stuff that is different
Bet you’ve already noticed what is different…we use prefixes to indicate how many of each atom we have
ex. SiO2 1 silicon atom + 2 oxygen atoms = silicon dioxide
ex. CO 1 carbon atom + 1 oxygen atom = carbon monoxide
ex. ICl4 1 iodine atom + 4 chlorine atoms = iodine tetrachloride
4
ex. P2O5 2 phosphorus + 5 oxygen = diphosphorus pentoxide
ex. N2O 2 nitrogen + 1 oxygen = dinitrogen monoxide
Number of Atoms
Prefix
1 mono-
2 di-
3 tri-
4 tetra-
5 penta-
6 hexa-
7 hepta-
8 octa-
9 nona-
10 deca-
5
Notes:
Mono is used on the 2nd element but not the 1st.
ex. CO = carbon monoxide
NO2 = nitrogen dioxide
N2O = dinitrogen monoxide
To avoid funny sounding words, drop the o and the a before oxide
ex. CO = carbon monoxide NOT carbon monooxide
ex. N2O5 = dinitrogen pentoxide
NOT dinitrogen pentaoxide

1. silicon tetrafluoride 7. tribromine octoxide 13. heptanitrogen pentaiodide 19. dinitrogen tetrahydride2. dinitrogen trisulphide 8. chlorine dioxide 14. dibromine pentoxide 20. tetraphosphorus decoxide3. hydrogen monobromide 9. nitrogen monoxide 15. oxygen difluoride 21. iodine heptafluoride4. diphosphorus pentoxide 10. diphosphorus pentasulphide 16. phosphorus pentaiodide 22. sililcon tetrabromide
Rules
1. The first element is named first, using the element’s name.
2. Second element is named like an Anion (suffix "-ide")
3. Prefixes are used to denote the number of atoms
4. "Mono" is not used to name the first element
5. Drop the o and the a before oxide

3 - SUBSCRIPTSThe formulas for BINARY ionic compounds tell us the RATIO between the number of cations and the number of anions.
The little numbers at the bottom chemical formulas are called SUBSCRIPTS. o The subscripts tell us the number of ions of each type o If there is no subscript, that indicates that there is 1 of that
particular ion
Ex. Sodium chloride NaCl Since there are NO subscripts at the bottom of the formula, that indicates that there is :
1 sodium ion for every 1 chloride ion
1 Na+ : 1 Cl
This ratio is shown in the diagram of a sodium chloride crystal lattice to the
left.
The smaller darker spheres represent Na+ and the larger lighter spheres represent Cl
Ex. Sodium sulphide Na2S The Na has a subscript of 2 and the S has no subscript
indicating that there are:
2 sodium ions for every 1 sulphide ion
2 Na+ : 1 S2
This ratio is shown in the diagram of a sheet of Na2S to the left.
Only 1 sheet is shown, rather than a more realistic 3 dimensional lattice because it gets really hard to draw!!

Something really neat to notice here!
If you have 1 Be2+ the total positive charge is 2+ …so in beryllium sulphide, BeS,
the positive charges exactly balance
If you have 1 S2 the total negative charge is 2 the negative chargesnet charge = 0
If you have 2 Li+ the total positive charge is 2+ …so in lithium oxide, Li2O,
the positive charges exactly balance
If you have 1 O2 the total negative charge is 2 the negative chargesnet charge = 0
If you have 1 K+ the total positive charge is 1+ …so in postassium bromide, KO,
9
1 Be2+ : 1
2 Li+ : 1
3 Mg2+ : 1 P3
1 K+ : 1
the positive charges exactly balance
If you have 1 Br the total negative charge is 1 the negative chargesnet charge = 0
If you have 3 Mg2+ the total positive charge is 6+ …so in magnesium phosphide, Mg3P2,
the positive charges exactly balance
If you have 2 P3 the total negative charge is 6 the negative chargesnet charge = 0
Now you try
Calcium fluoride CaF2 1 calcium ion for every 2 fluoride ions1 Ca2+ : 2 F
Total positive charge = _ 2+ _ _ 2 _= Total negative charge
Net charge = __0__
Barium oxide BaO 1 barium ion for every 1 oxide ion1 Ba2+ : 1 O2
Total positive charge = ______ ______ = Total negative charge
Net charge = _______
Aluminum nitride AlN 1 aluminum ion for every 1 nitride ion1 Al3+ : 1 N3
Total positive charge = ______ ______ = Total negative charge
Net charge = _______
Zinc phosphide Zn3P2 3 zinc ions for every 2 phosphide ions3 Zn2+ : 2P3
Total positive charge = ______ ______ = Total negative charge
10
Net charge = _______
In fact for ALL COMPOUNDS, the net charge = 0 . We can use this fact to do several things, one of which is…
PREDICTING THE CHARGE OF A TRANSITION METAL ION
Ex. What is the charge of iron in the compound FeO?
The formula tells us we have 1 iron ion and 1 oxide ion
We know that the oxide ion has a charge of 2 (from its position on the periodic table).
Therefore our 1 iron ion must have a charge of 2+ to balance out the 1 oxide ion, 2Ex. What is the charge of the iron ion in the compound Fe2O3 ?
Let’s do it this time by drawing out how many ions of each type we have (2 irons and 3 oxides)
Fe O2 I’ve included the charge of oxideFe O2 because we already know it.
O2 We’ll use it to find the total negative charge.
6 + 6
We can tell, then, that the total positive charge must be 6+ , to exactly balance the 6 .
Since we have 2 iron ions, each must have a charge of 3+ to give us a total positive charge of 6+
Fe3+ O2
Fe3+ O2
O2
6 + 6
Ex. What is the charge of the copper ion in the compound CuCl2 ?
Cu ClCl
11
2+ 2 our 1 copper ion has a charge of 2+ (Cu2+)
Ex. What is the charge of copper in the compound Cu2S ?
Cu S2
Cu
2+ 2 each copper ion has a charge of 1+ (Cu+)
to give a total positive 2+ charge
Ex. What is the charge of lead in the compound PbS2 ?
Pb S2
S2
4+ 4 our 1 lead ion has a charge of 4+ (Pb4+)
12
MULTIVALENT IONS
You may have noticed that in one compound, iron had a charge of 2+ and in another 3+.
Many of the transition metals (and a few others under the staircase) can have different charges depending on how many electrons they lose when they form a bond. We call these elements “multivalent”.
When writing the FORMULA for such ions, it is easy to tell the difference between them.
Ex. Cu+ Cu2+
We also need a way to tell the difference between them when we name them. We use ROMAN NUMERALS placed in BRACKETS to do this.
Ex. Cu+ is copper with a 1+ charge, so we call it the copper (I) ion
Cu2+ is copper with a 2+ charge, so we call it the copper (II) ion
Ex. Fe2+ is iron with a 2+ charge, so we call it the iron (II) ion
Fe3+ is iron with a 3+ charge, so we call it the iron (III) ion
Ex. Au+ gold (I) ion
Au3+ gold (III) ion

4 - ROMAN NUMERALS
I II III IV V VI
Roman numerals are used ONLY for cations…never anions
Roman numerals are used ONLY for multivalent cations…never for monovalent (simple) cations
Look at your NEW periodic table to see if more than one possible charge is listed for your cation. If so, it is multivalent…use a roman numeral. If not, it is monovalent. DON’T use a roman numeral.

6 - Naming Nonbinary Ionic Compounds
Ionic compounds with polyatomic ions
RECALL: Binary ionic compounds are made of _______ elements.
The cation (+) is a metal / nonmetal ion.
The anion () is a metal / nonmetal ion.
NEW: Nonbinary ionic compounds are made of _________________ elements.
The cation (+) can be a metal / nonmetal ion, or a POLYATOMIC ion
The only polyatomic cation is ammonium, NH4+
The anion () can be a metal / nonmetal ion, or a POLYATOMIC ion
There are many polyatomic anions
RECALL: When naming binary ionic compounds…
1) name the cation (metal ion), which is the same as the name of the element,
using ROMAN NUMERALS for multivalent cations
2) name the anion (nonmetal ion) by changing the ending of the element to “ide”
Ex. NaCl sodium chloride FeF3 iron (III) chloride
MnO2 manganese (IV) oxide MgO magnesium oxide
NEW: When naming nonbinary ionic compounds…
1) name the cation (metal ion OR ammonium NH4+)
2) name the anion (nonmetal ion OR polyatomic ion)
30
- if the anion is a single element, change the ending to “ide”
- if the anion is a polyatomic ion, look up the name on the PAI chart
Ex. NH4Cl ammonium chloride Fe(CN)3iron (III) cyanide Mn(CO3)2 manganese (IV) carbonate MgCO3 magnesium carbonate
31
Where does the cation end in the formula?
After the metal ion OR After NH4+
With the exception of NH4+, the cation is always just one element long. So when the first element ends, the cation ends.
After the cation, what does the rest of the formula mean?
The rest of the formula is the anion.
You will only EVER have one cation to name and one anion to name.
Examples:
AlPO4 cation = aluminum “aluminum phosphate” cation anion anion = phosphate
(NH4)2O cation = ammonium “ammonium oxide” cation anion anion = oxide
KNO2 cation = potassium “postassium nitrite” cation anion anion = nitrite
Mg(ClO3)2 cation = magnesium “magnesium
chlorate” cation anion anion = chlorate
NH4F cation = ammonium “ammonium fluoride” c ation anion anion = fluoride
NH4NO3 cation = ammonium “ammonium nitrate” c ation anion anion = nitrate
32
Now you try. For now just identify the cation and the anion:
Highlight (or put a box around) the cation. Everything to the right of the cation is the anion.
NaHCO3
CaCO3
Mg(OH)2
(NH4)2SO4

Now name the compound by naming the cation, then naming the anion:
ex. NaHCO3 Na+ = sodiumHCO3 = bicarbonate “sodium bicarbonate”
or HCO3 = hydrogen carbonate “sodium hydrogen carbonate”
Note: HCO3 , HSO3 , HSO4 and HS have to choices for names. Either bi________________
or hydrogen ____________________. Either is fine, but don’t use both!i.e. NOT sodium hydrogen carbonate bicarbonate
ex. CaCO3 Ca2+ = calcium CO32 = carbonate
“calcium carbonate”
ex. Mg(OH)2 Mg2+ = magnesium OH = hyroxide“magnesium hydroxide”
ex. (NH4)2SO4 NH4+ = ammonium SO4
2 = sulphate“ammonium sulphate”
ex. Ag2CrO4 Ag+ = silver CrO42 = chromate “silver
chromate”
