1. Using the Periodic Table
An Introduction

2. What is the Periodic Table?
It is a list of elements.
The arrangement of the elements is a guide to the chemistry of those elements.
It is also a guide to the properties of those elements.

3. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”

4. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”

5. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Alkali metal group

6. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Alkaline earth group

7. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Halogen group

8. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Noble gas group

9. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Each of these groups has its own particular chemistry.

10. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Alkali metals form ions with a single positive charge.

11. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Each alkaline earth metal forms ions with two positive charges.

12. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Each halogen forms ions with a single negative charge.

13. The Arrangement of the Table
The Table has vertical columns called “groups” or “families.”
Each noble gas is unreactive.

15. The Arrangement of the Table
The Table has horizontal rows called “periods.”

16. The Arrangement of the Table

The Table has horizontal rows called “periods.”
Third period

19. The Arrangement of the Table
The Table has horizontal rows called “periods.”
Fourth period

20. The Arrangement of the Table
The Table has horizontal rows called “periods.”
Fifth period

21. The Arrangement of the Table
The Table has horizontal rows called “periods.”
Sixth period

22. The Arrangement of the Table
The Table has horizontal rows called “periods.”
Seventh period

23. The Arrangement of the Table
The Table has horizontal rows called “periods.”

24. The Arrangement of the Table
The Table has horizontal rows called “periods.”
We see a gradual change in the properties and reactivities as we move across a period. We will explore this more in Unit 1b.

The table is also divided by the type of element.
There are metals.
There are non- metals.

29. The Arrangement of the Table
The table is also divided by the type of element.
There are metals.
There are non- metals.
There are metalloids.

30. The Arrangement of the Table
The table is also divided by the type of element.
