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.

Ionic and Covalent Compounds Lab 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.

Exit Ticket • What are the properties that can be used to distinguish between ionic and covalent compounds in lab?
