Lesson Plan: Covalent Bonding Chemistry • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe covalent bonding in terms of the electrostatic attraction between atomic nuclei and pairs of shared electrons.
Objectives
Students will be able to
- recall the octet rule and its relation to the valency of an atom,
- describe how covalent bonding involves the sharing of electrons between atoms,
- describe how the electrostatic attractions between nuclei and the pair of electrons give rise to covalent bonding,
- draw Lewis structures to show covalent bonds between atoms,
- explain how the sharing of more than one pair of electrons can result in double and triple bonds,
- draw Lewis structures for simple covalent structures such as water, methane, ammonia, and carbon dioxide,
- describe the physical properties of covalent structures and how they differ from ionic compounds.
Prerequisites
Students should already be familiar with
- types of chemical bonding.
Exclusions
Students will not cover
- polar covalent bonds,
- dative/coordinate covalent bonds.
