3. RULES TO FOLLOW Name the elements in the order listed in the formula.
9.3
RULES TO FOLLOW
Name the elements in the order listed in the formula.
Use prefixes to indicate the number of each kind of atom.
Omit the prefix mono- when the formula contains only one atom of the first element in the name.
The suffix of the name of the second element is -ide.

4. Write the formulas for the following compounds
Let’s Practice!
Write the formulas for the following compounds
Nitrogen monoxide
Dinitrogen monoxide
3. Dinitrogen pentoxide

5. Let’s Practice Some More
Can you write the name from the formula?
P2O
O2Cl2
SF6

6. METAL to a NONMETAL Anytime you see a POLYATOMIC ION

Ionic Compounds
METAL to a NONMETAL Anytime you see a POLYATOMIC ION

7. Ionic Compounds Rules to Follow Cation(the metal) written first
9.2
Ionic Compounds
Rules to Follow
Cation(the metal) written first
Anion(the nonmetal) last (ending changed to –ide)
If metal is a transition metal (or in a skipped column) it needs a roman numeral to tell everyone it’s charge!
Do NOT include charges when writing final formula

8. Ionic Compounds MORE HELPFUL HINTS
9.2
Ionic Compounds
MORE HELPFUL HINTS
Use periodic table to determine charges
Add subscripts as needed to balance the charges to ZERO
If roman numeral needed- it is the CHARGE

9. PRACTICE MAKES PERFECT
Write the formulas for each of the following
Lithium oxide
Calcium nitride
Aluminum chloride
Iron (II) oxide
Cobalt (II) bromide

10. More Practice = More Perfect
Write the names of each of the following
CaBr2
Al2O3
CsCl
NiCl2
CuO

Compounds With Polyatomic Ions
Hints for POLYATOMICS
Polyatomic ion – ion with multiple atoms with a charge
Listed in periodic table
Use ( ) for more than one polyatomic
Charges must still balance to zero!
