Lesson Plan: Ionic Bonding Chemistry • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe ionic bonding in terms of electrostatic attraction and use it to explain the properties of ionic structures.
Objectives
Students will be able to
- recall the octet rule and its relation to the valency of an atom,
- recall the formation of cations and anions from the loss or gain of electrons,
- describe how ionic bonding involves the transfer of electrons between atoms,
- describe how the electrostatic attraction between ions of opposite charges gives rise to ionic bonding,
- draw Lewis structures to show ionic structures and bonds,
- describe the physical properties of ionic structures and how these arise from their bonding,
- recognize that ionic compounds have a regular lattice structure, using sodium chloride as an example,
- recognize the 2D and 3D structures of ionic compounds, using sodium chloride as an example,
- identify the formula unit for an ionic compound.
Prerequisites
Students should already be familiar with
- types of chemical bonding,
- ions.
Exclusions
Students will not cover
- crystal structures,
- ionic equations.
