Nitrogen 
Phosphorus 
Oxygen 
Sulfur 
Selenium 
Fluorine 
Chlorine 
Bromine 
Iodine 

3. Ionic Compounds #1 – Binary Naming Practice
Drag and drop the correct
Name for each element.
MgCl2
Al2N3
KBr

4. Ionic Compounds #2: Naming with Polyatomic Ions
Watch the video about naming compounds with polyatomic ions
In them.
Polyatomic Ions: A group of atoms that are covalently bonded together and work as one ‘family’ with a charge.
If the formula has 3 or more elements, you have a polyatomic ion. Circle all of the polyatomic ions present.
Al(NO2) NaCl NaOH CrF3
(NH4)2S BaCl KClO AlF3

5. Ionic Compounds #2: Naming with Polyatomic Ions
Steps for naming compounds with polyatomic ions
Example: Name NaOH
If the metal is a “main-group” metal. Name it.
Sodium
B. Name the polyatomic ion.
Hydroxide
C. Write the full name
Sodium hydroxide

6. Ionic Compounds #2 – Polyatomic Naming Practice
Drag and drop the correct name for each of the compounds below
MgClO3

KCN

7. Ionic Compounds #3 – “Special” Metal Naming Practice
Watch the following video for help with naming “special” metals:
CuClO3
ZnS2
Pb3N4
CuSO4

8. Ionic Naming Flowchart – Copy & Save in Your Notebook
How many different elements? 2
(binary)
Is cation a “main-group” metal?
Yes
Name the metal. Then name anion using the –ide ending No
Name the metal– include roman numeral. Then name anion using –ide ending
3 or more (have polyatomic)
Name the metal. Then name the polyatomic
Name the metal – include roman numeral. Then name polyatomic

*Please raise your hand when finished and a teacher will be by to check your work 

12. Covalent Naming – Binary compounds
Covalent bonds happen between? Highlight one. a). Metal and non-metal b). Two Non-metals c). Two Metals Put a check by the statements that are true: Covalent bonds do have ions. Covalent bonds do not have ions. Covalent bonds do have charges. Covalent bonds do not have charges.

13. Covalent Naming Prefixes – Print & Put in Your Notebook

14. Covalent Naming Practice
SiO­2
BBr3
dinitrogen monoxide
tetraphosphorus triselenide

15. Naming Acids – Two Types
Oxyacids
Three or more elements
H+ bonded to a polyatomic ion
H+ is always written first
H2SO4
H2SO3
H2CO3
H3PO4
Binary Acids
Only 2 elements
H+ bonded to nonmetal
H+ is always written first
HCl HF HI
HBr

16. Acids #1 – Naming Oxyacids
Polyatomic ends with –ate
H2SO4
Polyatomic is: sulfate
To name:
Change “-ate” to “-ic”
Add the word “acid”
sulfuric acid
Polyatomic ends with –ite
H2SO3
Polyatomic is: sulfite
To name:
Change “-ite” to “-ous”
Add the word “acid”
sulfurous acid

17. Acids #1 – Naming Oxyacids Practice
H2CO3
H3PO4
Acetic acid
Hypochlorous acid

18. Acids #2 – Binary Acids Example: HF To Name:
Use the prefix hydro- for the first part of the name.
hydro________
Look at the second element, the nonmetal. Use the root name of the nonmetal. In this case, the nonmetal is fluorine, so we use the prefix fluor-.
hydrofluor-
Add the –ic ending to the nonmetal root name. Fluor- would add –ic to become fluoric.
hydrofluoric
Add acid as the second name.
 hydrofluoric acid
Example: HF

19. Acids #2 – Naming Binary Acids Practice
H2S
HCl
Hydronitric acid
Hydrobromic acid

20. Naming Acids Flowchart
Ex: H3PO3
How many different elements? 2
(binary acid)
Hydro______ic acid
(put root word of 2nd element)
3 or more
(have polyatomic - Oxyacid)
Does the polyatomic end in –ite or -ate
-ite
*Name polyatomic, change “-ite” to “-ous”
*Add word “acid” to name
-ate
* Name polyatomic, change “-ate” to “-ic”

23. Thank You!
It has been great working with you for naming and writing formulas for ionic and covalent compounds! You will use this for the rest of module 3, module 4 and most of segment 2.
Please use our other recorded teaching sessions for the other lessons. Don’t forget that you can use them to review previous lessons too!
