Lesson Plan: Ionic Bonds

vs Covalent Bonds

Lesson Title: Ionic Bonds vs Covalent Bonds

Grade/Age Level:

high school chemistry, ages 15-18

Subject Area:

high school chemistry

Time allotted for the lesson:

2 class meetings

Day 1: What are ions and how they form

Day 2: Introduce periodic table chart of electronegativities and the chart I made to

help students see if two atoms will tend to form ionic or covalent compounds

Short description of lesson:

In this lesson, the learners will be introduced to the idea that the electrons surrounding

the nucleus can either be gained or lost. If the number of electrons stays the same, then

perhaps the atoms are involved in a covalent bond.

To get an idea of whether two atoms will form an ionic or a covalent bond, they can

use a periodic table that lists electronegativity values. Based on the difference in

electronegativity values, the atoms will either swap electrons or share them.

California Curriculum Standards met in this lesson:

Chemical Bonds

Biological, chemical, and physical properties of matter result from the ability of atoms to

form bonds from electrostatic forces between electrons and protons and between

atoms and molecules. As a basis for understanding this concept:

Students know atoms combine to form molecules by sharing electrons to form

•

covalent or metallic bonds or by exchanging electrons to form ionic bonds.

Students know salt crystals, such as NaCl, are repeating patterns of positive and

•

negative ions held together by electrostatic attraction.
