Reflection: Staircase of Complexity Metallic and Covalent Bonds- Formation and Naming - Section 2: Engage


Over the years I have found that students tend to get overwhelmed with this unit because it is very information rich.  They especially get confused between the various types of bonds and which properties, Lewis structures, naming, etc. goes with each type.

Therefore, I find it really important to continuously give students an opportunity to differentiate between the types of bonds.  In this particular lesson I have students review properties of ionic BEFORE we delve into covalent and metallic bonds.  I find that this helps to prevent some of the confusion and solidify the differences between the types.

Additionally, by having students perform Periodic Table Aerobics throughout the unit they are being reminded of the basic differences between the bonds.

Metallic and Covalent Bonds- Formation and Naming

Unit 3: Unit 3: Bonding & Periodic Table Trends
Lesson 6 of 9

Objective: Student will be able to explain the characteristics of metallic and covalent bonds including how to name covalent compounds through taking notes, doing whiteboards, and performing practice questions.

Big Idea: Metallic bonds involve delocalized electrons among metals while covalent bonds involve nonmetals which share electrons in molecular orbitals.
