Lesson 23: Alchemy of Paint
Transition Metal Chemistry
Key Question
What types of compounds are made from transition
metals?
Objectives:
•
•
•
recognize transition metal compounds
determine the charge on transition metal ions
Name compounds with transition metals
Lesson 23 Notes:
a.) Transition metals:
• In the middle of the periodic table
• Need to have a “middle” name (Roman
Numeral)
• Ions can have multiple charges
• Roman numeral tells which charge is being
used
Notes (cont’):
b.) Charges on Transition Metals
• Use charges you know (from the main group
elements) and the “rule of zero” to work
backwards to find charges on transition
elements
Iron (III) Oxide
Iron (II) Oxide
c.) ONLY transition elements need roman
numerals!!!!
• DO NOT use them for main group
elements
NaCl = sodium chloride
MnCl2 = Manganese (II) chloride
Check-in 23:
1. What is the name of the compound,
CuO?
2. What is the formula for Zinc (II) chloride?
