Ionic and Covalent Compounds
Bonding Lab
• Objective
– Today I will be able to:
• Explain the movement of electrons in metallic bonds
• Analyze experimental data to differentiate between ionic and covalent compounds
• Correctly name and write formulas for ionic and covalent compounds
• Evaluation/ Assessment
– Informal assessment – Listening to group interactions as they
complete the ionic and covalent compounds lab and the naming
compounds practice.
– Formal Assessment – Analyzing student responses to the lab questions
and the naming ionic and covalent compounds practice.

Metallic Bonding Notes
Metallic Bonds
• Loosely bound valance electrons which are
called mobile electrons because they are free
to move around
– delocalized
• Allow the transition metals and rare earth
metals to have multiple charges
Electron Movement in Metallic Bonds
Properties of Metallic Bonds
•
•
•
•
Solids at room temperature (except Mercury)
Ductile
Malleable
Good conductors
Ionic and Covalent Compounds Lab
Safety
• Must wear goggles, aprons and closed toe
shoes to participate
• Instead of a bunsen burner, we will be melting
the compounds on a hot plate, covered in
Aluminum foil
• Hot plates are HOT, do not touch even after
you turn them off
• Dispose of all solid compounds in the trash
can and all liquids down the sink.

Move into groups assigned by Ms. Ose
Work through the lab
If you have questions please ask!
Do not forget to explain why in your conclusion
statement. Listing the ionic and covalent compounds
alone will not result in a good score on this lab
• When you finish the lab, you may begin to work on
the Naming Covalent Compounds Practice that you
have on the back of the Ionic compounds practice.
Naming Covalent Compounds
Practice
When you finish the lab complete the
practice with the people around you.
Ionic and Covalent Compounds
Practice
Complete the practice with the people
around you. Whatever you do not finish
in class will become homework. We will
review next class.

distinguish between ionic and covalent
compounds in lab?
