How do you use an ionic name to create the ionic compound with transition metals?

Now let’s try answering the problems in the other direction (having the ionic name and creating the compound). Remember to count up all the charges and total them to zero.

 

Examples: Give the chemical formula of each compound using a regular periodic table. Don’t forget to use the ion periodic table if you need it. VIDEO Ionic Naming With a Transition Metal Examples Video 2.

Nickle (I) Fluoride	NiF
Iron (III) Phosphide	FeP
Silver (II) Bromide	AgBr2

 

VIDEO Ionic Naming Demonstrated Example 5: Give the chemical formula of each compound using a regular periodic table. Don’t forget to use the ion periodic table if you need it.
