Compound names and formulas
Naming ionic compounds

The first part of the name is the: __________________ which is from the __________ side of the periodic table.

The second part of the name is the: __________________ which is from the __________ side of the periodic table.

Also, you have to change the name on the second part.  For example:
Chlorine becomes ____________
Oxygen becomes ____________
Sulfur becomes ____________
Nitrogen becomes ____________

Some metals of the same element can have different charges.  The charge is expressed as a ________________ in the name.

For example:
Cu+ is _________________________
Cu2+ is _________________________
_____________________ is Iron(II)
_____________________ is Iron(III)

Determining the charge from a formula.
Look at the anion to determine the charge.
Multiply that charge by the number of anions present.
Divide that total by the number of cations present.
Now you have the charge on the cation.

Example:
Fe2O3
What is the charge on the anion? _____
What is the total negative charge? ______
How many cations are present? ______
What is the charge on the cation? ______

What are the formulas for the following?:
Lithium oxide_____________
Beryllium chloride_____________
Titantium(III) nitride_____________
Cobalt(III) hydroxide_____________

Naming covalent compounds
