FIRST OF ALL…
Is it a compound?
YES
NO
INVALID CHOICE
You have to go back
lol 
DOES IT HAVE…
Metals and
Nonmetals and/or
Polyatomic Ions?

2 or more
nonmetals?

Then its IONIC!
Then its COVALENT!

IONIC
IS IT…

(Positively Charged Polyatomic
Ion)
(Negatively Charged Polyatomic

Naming Rules:
 Polyatomic ion comes
first
 Negatively charged
element follows
Naming Rules:
 Positively charged
element comes first
 Polyatomic ion follows

Criss Cross
Method
Naming Rules
First Element Name
 Simply name the
element used first!
Second Element Name
 Chop off the ending and
add –ide!
FINAL RESULT!
CRISS CROSS METHOD
The compound needs to be stable!
When you put the ions together, the overall charge still needs to
equal zero. You write the cation (positve ion) first, including its
charge. Next, you write the anion (negative ion) including its
charge. You “criss cross” the charges to form subscripts on the
opposite ions!

NAMING RULES FOR IONIC BONDS
You need to write the cation first (Refer to Periodic Table for
its name) . If the cation is a metal that contains multiple
charges, you have to specify the charge. You do this by
writing the number as a Roman Numeral in
parenthesis after the cation.
Next, write the anion (Refer to Periodic Table for its name) .
Drop the ending, and add the sufix –ide. If there is a
polyatomic ion present, refer to polyatomic ion sheet
for its name.

COVALENT
Naming Rules
First Element Name
 See naming rules
 Use appropriate element
name and prefix.
Final Results!
Second Element Name
 See naming rules
 Use appropriate element
name and prefix.
 Don’t forget- chop of f
ending and add –ide!
NAMING RULES FOR COVALENT BONDS
First, the cation (positive ion) should be named. Do
not cut off any parts of the element’s name.
 If there is a subscript of 2 or more, see Prefix Char t
Next, the anion (negative ion) should be named.
 If the element begins with a vowel, the (a) and (o) are dropped from
the end of the prefix
 If there is a subscript of 2 or more, see Prefix Char t
