1. Naming Ionic Compounds

2. Ionic Compounds
An ionic compound is a bond between a metal and a non-metal.
Electrons are stolen and given.

3. Name to Formula Step 1: Identify the charge of each element.
ex: Sodium Chloride
Na1+ Cl1-
Step 2: Switch the exponent values (drop the charge) to subsets of the other element.
ex: Na1 Cl1
Step 3: Simplify and combine abbreviations.
ex: NaCl

4. Formula Rules Simplify the number of elements:
If the numbers are the same they disappear.
If the numbers can be factored, reduced.

5. Rules in Naming Cations then Anions Cations: [Element Name] “Ion”
Anions: [Stem of element name]+”ide
When combining the two the word “Ion” is dropped.

6. Formula to Name
Step 1: Switch the subsets to exponents of the other element.
ex: Li2O -> Li1 O2
Step 2: Label the first element as a cation (+) and the second as a anion (-).
ex: Li1+ O2-
Step 3: Make sure the charge of each is correct by looking at oxidation values.
Step 4: Identify ions following rules for anions and cations.
ex: Lithium Oxide

7. Identifying Names
If charges do not match the oxidation value of the element:
Determine the needed value
Multiply both charges by that value
If the cation is a transition metal with multiple possible charges, put the charge as roman numerals in parenthesis after the name.
