6. Identifying & Naming Binary Ionic
These compounds have:
2 elements (“binary”)
A metal & a non-metal (“ionic”)
To name these compounds:
Write the name of the metal (the cation)
Write the name of the non-metal (the anion) with the suffix “-ide”
The subscripts in the formula do not matter when naming this type

7. Example #1
NaCl

8. NaCl Example #1 Sodium Chloride Cation Anion “Sodium”
“Chlorine” becomes “Chloride”
Sodium Chloride

9. Example #2
CaBr2

10. CaBr2 Example #2 Calcium Bromide Cation Anion “Calcium”
“Bromine” becomes “Bromide”
Calcium Bromide

11. Example #3
K2O

12. K2O Example #3 Potassium Oxide Cation Anion “Potassium”
“Oxygen” becomes “Oxide”
Potassium Oxide

18. Identifying & Naming Binary Ionic
These compounds:
End in “-ide” (except “hydroxide and cyanide”)
Do NOT contain covalent prefixes
To write these formulas:
Write the symbol & charge of the first element (the metal, cation)
Write the symbol & charge of the second element (the non-metal, anion)
Add more of the cations and/or anions to have a neutral compound
Use subscripts to show how many of each type of ion is there.

19. Example #1
Sodium chloride

20. Example #1
Na+1
Cation
Sodium chloride
Anion
Cl-1
NaCl

21. NaCl Example #1 Sodium chloride Cation Anion Na+1 Na+1Cl-1 +1 + -1 = 0
The compound is neutral…no subscripts are needed.
Cl-1
NaCl

22. Example #2
Calcium bromide

23. Example #2
Ca+2
Cation
Calcium bromide
Anion
Br-1

24. CaBr2 Example #2 Calcium bromide Cation Anion Ca+2 Ca+2Br-1
= +1
Anion
Ca+2Br-1Br-1
Br-1
= 0
CaBr2
The subscript “2” is used to show that 2 anions are needed.
