Chem – Naming Ionic Compounds with Transition Metals Part 2

What sections should I know before attempting to learn this section?

—> Covalent, Ionic, and Metallic Bonds

—> Forming Ionic Compounds

—> Breaking Apart Ionic Compounds
 

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.
