    • Bell ringer (verbal): What is the formula for Silver (III) oxide?

    • Writing names for transition metal compounds

      • Write the names for each element together, leaving space for the Roman Numeral after the transition metal

      • Figure out how many electrons total were taken by the non-metal element using the periodic table and the number of atoms of that element

      • Divide that number by the number of transition metal atoms to find out how many electrons each atom gave away

      • Write that number as the Roman Numeral after the transition metal

      • Example: Fe2O3

        • Looking at the periodic table, Oxygen has 6 valence electrons. Each atom will take 2 more electrons. Since there are 3 oxygen atoms, a total of 6 electrons will be taken.

        • The iron atoms must have given up a total of 6 electrons. Since there were 2 iron atoms, each must have given up 3 electrons

        • Name of compound is Iron (III) oxide

  • Naming transition metals assignment - write the name of each compound

      1. CuO

      2. Cu2O

      3. FeN

      4. Cr2S3

      5. ZnCl2
