Discovering Chemical Bonds

Discovering Chemical Bonds

Learning Objective

At the end of the lesson, you will be able to understand what chemical bonds are and identify different types of chemical bonds.

What do you already know about chemicals?

What are Chemical Bonds?

Chemical bonds are forces that hold atoms together to form molecules. They are like glue that keeps atoms connected.

Types of Chemical Bonds

There are three main types of chemical bonds: ionic bonds, covalent bonds, and metallic bonds.

Ionic Bonds

Ionic bonds occur when one atom gives electrons to another atom. This creates positively and negatively charged ions that attract each other.

Covalent Bonds

Covalent bonds occur when atoms share electrons. This allows them to fill their outermost energy levels and become stable.

Metallic Bonds

Metallic bonds occur between metal atoms. The outer electrons of metal atoms are free to move around, creating a 'sea' of electrons that hold the metal atoms together.

Interactive Activity

Let's play a game to identify different types of chemical bonds. I will show you some examples, and you need to tell me which type of bond it represents.

Summary

Chemical bonds are forces that hold atoms together to form molecules. There are three main types: ionic bonds, covalent bonds, and metallic bonds.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
