Updated: Now includes print and digital options for the lesson. Perfect for distance learning or the paperless classroom. Interactive student notes, exit ticket, and homework for Google Slides™.
This lesson introduces the third of the major types of bonding – metallic bonding. Most students are aware of the properties of metals. The main concept of this lesson is to provide explanation, at the atomic level, for these properties. The lesson also discusses alloys. Alloys are studied in more depth during the solutions unit. For now, students will explain why alloys are important, and how they are formed. The lesson does not go into the different arrangements in alloys: substitutional, interstitial, or substitutional/interstitial.
Lesson Objectives:
* Describe the “sea of electrons” model of metallic bonding
* Explain why metals are good conductors of thermal energy and electricity
* Explain why metals are malleable and ductile
* Describe why ionic bonds are not malleable and ductile
* Explain why metals are shiny
Prior Knowledge:
Atomic Structure and Ionic Bonding
Lesson Duration: 1 class period

Note on the PowerPoints: The PowerPoints included in this product are editable. They are also animated, which means that they may appear busy or overlapping in the slide edit mode, but will be awesome in the slide show mode! Please don’t edit the PowerPoints until you have seen them in the slide show mode!
This lesson is appropriate for grades 9-12 chemistry
This will be a lesson you will want to use year after year!
