Suggested problems from the textbook "Chemistry" (Prentice Hall). These are only from the Assessment and Standardized Test Prep found at the end of the chapters. There are also questions available at the end of each section (in the textbook) for more practice.
Review Bonding IMetallic vs. Ionic vs. Covalent
• Properties (metallic and ionic)
• Nomenclature (naming metallic and ionic)
Introduction to Bonding
Ionic • M+ NM-
• Ionic Compounds
• Cation and Anion
• Valence electrons lost and
gained
Metallic• NM – NM
• Molecules
• Elements, O2
• Compounds, H2O
• Valence electrons shared
Covalent• M% and M %
• Alloys
• Valence electrons free-
flowing
• "Covalent in nature"
Metallic Bonds
Delocalized Electrons
"Covalent" in nature
EXP Gold RushOne Note: Content Library: Unit 4: Topic 2
EXP Gold Rush
Students must write a full formal lab
report.
Use the Reaction in a Bag as a
reminder of format and charts
(materials and SDS).
Prep THROUGH Data Table.
(see next slide for details)
Lab Report Reminders
• Hypothesis: Be specific about what you are doing (if...) and what you expect (then...)
• Materials: Must be in a chart form
• Pennies are chemicals, also.
• Steel Wool is being used as a tool (to clean pennies) so can be listed as a tool or as a chemical.
• Safety: Must be in a chart form
• Even though Steel Wool and Water are also chemicals, only find the SDS for Zinc and sodium hydroxide (and ADD the additional information noted on the lab into the chart where it belongs)
• Do NOT forget to add a section about the dangers/hazards and precautions of/ for using a hot plate.
• Permission Granted to Copy:
• Concept and Skills
• Procedure Steps 1 – 8
• Complete through the data table.

Nomenclature 1Binary Ionic Compounds
Binary Ionic Compounds (multiple oxidation states)
Practice/ HomeworkDUE Thurs, 2/6/2020
Select 20 (minimum) Binary Ionic
Compounds
1. For 10, Construct Formula's from
Chemical names
2. For 10, Deconstruct Formulas to
create Chemical names
Review: Binary Ionic
Constructing Chemical Names
Metals w/ Known Oxidation States
Metals w/ Known Oxidation States (aka. "Fixed")
Metals w/ Multiple Oxidation States(aka. "variable")
Example: MnF3
How to• Step 1: Deconstruct
• Step 2: Assign KNOWN charges to the NONMETAL
• Step 3: Add up negative charges
• Step 4: Equal to positive charges
• Step 5: Distribute positive charges
• Step 6: Write the name using Roman Numerals to identify the charge of the metal.
Example• Mn F
FF
• Mn F-
F-
F-
• _____________
3-
• 3+ 3-
• Mn 3+
