Main Group Metals
Any metal that is not a
transition metal
Check Point
Is Silver (Ag) a main group metal?
Check Point
Is Magnesium (Mg) a main group
metal?
How to Name Ionic Compounds??
[with main group metals]
Compound: NaCl
Step 1
Write the elemental
name of the cation.
Example: Na+1 → Sodium
How to Name Ionic Compounds??
[with main group metals]
Compound: NaCl
Step 2
Write the elemental
name of the anion.
Example: Cl-1 → Chlorine
How to Name Ionic Compounds??
[with main group metals]
Compound: NaCl
Change the suffix of
Step 3
the anion to “ide”
the anion is a
nonmetal
Example: Chlorine
Chloride
IF
How to Name Ionic Compounds??
[with main group metals]
Compound: NaCl
Step 4
Rewrite the name of the
compound
Example: Sodium Chloride
Exception

What if your anion is a polyatomic ion?

Write the name as it is on your list of
polyatomic ions.

Example: NO3-1 → Nitrate
Example: K2SO4
Cation → K + , Anion → SO4 -2
1.
Write the elemental name of the cation:
K +1 → Potassium
2.
Write the name of the polyatomic ion:
SO4 -2 → Sulfate
Answer: Potassium Sulfate
