this is a short presentation to help you prepare your lesson by incorporating computer in your teaching- when i see and do, i remember.

2. INTRODUCTION
• Living things are made of atoms but in most
cases those atoms are not just floating around
individually. Instead they are usually
interacting with other atoms.
• How do atoms interact with each other?

3. Review of relevant previous
knowledge of students
• Using oral questioning answer the following
questions;
1. what is an atom?
2. what is a molecule?
3. explain ionization energy in your own words?

4. LESSON OBJECTIVES
• By the end of the lesson, students will be able
to;
1. explain chemical bond and state the types
2. describe how ionic bond is formed using ball
and stick model
3. Interpret and analyze ionic bond in various
chemical bonds
4. state and explain physical properties of ionic
bond

5. Demonstration of chemical bond using
ball and stick model
• Ball and stick model is a model that is used to
show position of atoms and the bonds formed
between them in 3-dimension.
• These balls have different colors that show the
types of elements present in the bond

6. Chemical bonding
• Bond is something that fastens or holds things
together. A bond can be a relationship
between individuals example sisters.
• Chemical bond holds molecules together and
creates temporary connections that are
essential in life.
• Chemical bond is formed to achieve a more
stable outer electronic configuration.

7. Types of chemical bond
• The two main types of chemical bonds are;
1. interatomic or intramolecular bond:
it is a force that holds atoms together in
molecule. Also known a primary bond. Ionic
bond, metallic bond and covalent bond are
types of interatomic bond.

8. Types of chemical bond
2. intermolecular bond:
it is a force that holds molecules together. It is
also known as secondary bond. They include
electrovalent bond, covalent bond, hydrogen
bond and Van der Waal’s forces.

9. Students activity
• Using a five minute test explain in your words
three key terms that was mentioned during
the demonstration and explanation of
chemical bond.

10. Intramolecular bonds
(i)ionic bonds
• Let us watch a video on the nature and
formation of ionic bond

11. Physical properties of ionic bond
• They are crystalline solids at room
temperature
• They are soluble in polar solvents such as
water but insoluble in non polar solvents
• Ionic compounds have high melting and
boiling points due to the strong intermolecular
electrostatic forces

12. Students activity
In a group of five students answer the following
questions on a stick note
1. What is ionic bonds?
2. How is ionic bond formed between chemical
species?
3. Give 8 examples of ionic compounds in their
chemical formula and analyze the formation of
ionic bond in each compound.
4. State two properties of ionic bonds and explain
why?

13. Checking for understanding
• Each group’s stick note is pasted on the board
for whole class discussion facilitated by
teacher.

14. review
• Chemical bond holds molecules together and
creates temporary connections that are
essential in life. The types of chemical bonds
are;
1. interatomic or intramolecular bond
2. Intermolecular bond

15. review
• Ionic bond; it is an electrostatic force of
attraction between positively charged ion and
negatively charged ion. Example, NaCl(Na+ Cl-)
• They are crystalline solids at room
temperature
