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

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.

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+
