1. Naming Compounds
Ionic and Covalent

2. First thing first… Determine if the compound is Ionic or Covalent.
Ionic = Metal + Nonmetal
Covalent = Nonmetal + Nonmetal

3. Metal vs Nonmetal
Nonmetals
Metals

4. Metal vs Nonmetal
Nonmetals
Metals

5. Metal vs Nonmetal
Nonmetals
Metalloids
Metals

6. Ionic: Binary (2 elements)
Positive ion + Negative ion
Change ending to “ide”

7. Ionic Naming Subscripts have no affect on the name. Example:
NaCl = Sodium Chloride
CaCl2 = Calcium Chloride

8. Transition Metals
Roman Numerals are used to indicate the CHARGE of transition metals.
1 I
2 II
III
4 IV V VI
VII
VIII IX X

9. Transition Metal Example
Charge of Nickel (+3)
Nickel (III) Sulfide
Charge of Sulfur (-2)
Ni2S3

10. Polyatomic ions
An ion containing more than one atom.

11. Polyatomic ion Families

12. Common Polyatomic Ions
NH4+ ammonium
CN- cyanide
OH- hydroxide
NO3- nitrate
NO2- nitrite
SO4-2 sulfate
SO3-2 sulfite
PO4-3 phosphate
ClO3- chlorate
MnO4- permanganate
CO3- carbonate

13. Memorizing Polyatomics
OH NO SO CO PO
hydroxide nitrate sulfate carbonate phosphate

14. Using polyatomics +2 +3
Magnesium Phosphate
Mg PO4
Mg3(PO4)2

15. What to remember about ionic compounds
End in “ide”
Transition metals
Roman Numeral indicates charge
Polyatomic ions

16. Try a few Ionic Compounds
K3N __________________
CuOH __________________
FePO4 __________________
MgO __________________

17. Try it the other way Vanadium (III) sulfide _______
Manganese (II) phosphate _______
Sodium oxide _______
Lithium Fluroide _______

18. Covalent Naming Know your prefixes 1 Mono 2 Di 3 Tri 4 Tetra 5 Penta
6 Hexa
7 Hepta
8 Octa
9 Nona
10 Deca

19. diphosphorous trioxide
Use the prefixes
The prefix indicates the number of atoms of the element
Change the ending of the second compound to “ide”
Ends in “ide”
diphosphorous trioxide
2 Phosphorous atoms
3 Oxygen atoms

20. Use the prefixes Carbon dioxide
If the first element is singular do not use the mono prefix.
Ends in “ide”
Carbon dioxide
1 Carbon atoms
2 Oxygen atoms

21. Use the prefixes Carbon monoxide
If the second element is singular you must use the mono prefix.
Ends in “ide”
Carbon monoxide
1 Carbon atoms
1 Oxygen atom

22. Try a few Covalent Compounds
NF3 ___________________________
Si2Br6 ___________________________
N2O3 ___________________________
ClO2 ___________________________
CF4 ___________________________

23. Try it the other way now Hexaboron Silicide ______________
Dihydrogen monoxide ______________
Iodine pentafluoride ______________
Phorsphorous triiodide ______________
Carbon tetrachloride ______________

24. YAY!
You are now an expert at naming compounds 
