4.2 The Arrangement in the Periodic Table of Elements
1. Teacher informs the students that today they will be learning about one of the
most important table in our lives.
2. Students are informed that the table they are going to learn is Periodic Table.
3. Teacher informs the students the meaning of Periodic Table.
4. Teacher recaps the basic principle of arrangement of elements in Periodic
Table.
5. Teacher explains the arrangement in the Periodic Table. Arrangement of
elements are usually discussed in terms of

Groups

Periods

Proton Number

Electron Arrangement
6. Teacher shows to the students which one is Group and which one is Period in
the Periodic Table.
7. Teacher explains to the students the relationship between proton number and
position of elements in the Periodic Table.
8. Teacher emphasizes that valence electron can help us to determine the group
for the element. Meanwhile the number of shells we have can be used to
determine the period.
4.3 Elements in Group 18
1. Teacher asks the students to watch a video on YouTube.
2. The video explains about the physical properties of elements in Group 18 in
terms of density and boiling point.
3. The video informs the students about the practical use of Group 18 elements
in our daily lives.
4.4 Elements in Group 1
1. Teacher informs the students that in the third video provided, the students
will be learning about elements in Group 1.
2. Students are informed that going down the group, the atomic mass of the
element increases. This can affect the physical and chemical properties of the
element.
3. Teacher proceeds with lecture about physical properties first.
4. Students are informed that the physical properties are usually discussed in
terms of

Density

Appearance (Colour and Softness)

Boiling Point

Melting Point
5. Teacher explains to the students that going down the group

Density increases

Boiling Point and Melting Point decreases
6. Teacher explains to the students the reason why Melting Point and Boiling
Point Decreases.
7. Students are informed that going down the group, the softness of the element
increases. Therefore it is easier to cut the element.
8. Teacher shows a short clip about an experiment cutting the element in Group
1.
9. Teacher summarises the important keys about physical properties of elements
in Group 1.
10. Teacher proceeds with chemical properties of elements in Group 1.
11. Chemical properties usually discussed in terms of its reactivity.
12. Teacher informs the students, when going down the group, the reactivity
increases.
13. Students are explained on the reason why reactivity increases when going
down Group 1.
14. Teacher concludes the important keys on chemical properties.
15. Teacher informs the students that most of the smartphone in the market are
using Lithium Ion Battery. This battery requires extra care.
16. Students will be watching a short clip that shows ways to take care of Lithium
Ion Battery.

1.
Explain why Neon, Ne does not react with other elements.
Compare the boiling point of Helium and Argon. Explain.
Why is sodium more reactive than lithium?
Teacher emphasizes that elements in the Periodic Table are arranged in
ascending order of atomic mass.
2. Teacher reminds the students that valence electron can be used to determine
the group for the elements. Meanwhile to determine period, number of shells
can be used.
3. Students will be informed once again that the Group 18 elements are stable
because it has octet or duplet valence electron.
4. Teacher reminds the students the boiling point and density of elements in
Group 18 will increase as going down the group.
5. Students are informed once again that physical properties in Group 1 are
discussed in terms of Boiling Point, Melting Point, Density and Appearance.
6. Going down the group, melting point and boiling point will decrease. Density
and softness will increase.
7. In terms of chemical properties, teacher highlights to students that they have
to know how to describe reactivity of the element when going down Group

Students are given the chance to watch a You Tube video
that explains ways to take care of Lithium Ion Battery.
This is important as most of the smartphone designed
nowadays, they are using built-in Lithium Ion Battery.
Proper care of the battery can increase the life-span of
the battery. Besides that, it can also prevent from
unwanted incident such as battery explosion from

occur since Lithium able to accept current rapidly which
can cause the battery to become unstable, thus leading to
explosion.
