1. Lesson Objective:
You will be able to identify the location of metals, nonmetals, and metalloids on the Periodic Table.

2. How is a grocery store organized??
I have students list out all the different types of areas in a grocery store. I then ask them why they are in this specific order to get them thinking about organization and how it allows us to find things easily.

3. Similar items are grouped together in aisles or departments!
Produce department
Frozen foods
Cereals
Baked goods
Baking ingredients
Canned fruits and vegetables
Toiletries
Snacks (chips, cookies, candy)
Drinks

4. Aisles and departments are then organized even more!
Small vs. Large cereal boxes
Fruits vs. Vegetables
White bread vs. Wheat bread
Diet soda vs. Regular soda
Organic meat vs. Regular meat

5. Before the Periodic Table
It was a mess!!!
Imagine going to a grocery store with no organization.
There was no organization of elements.
It was very difficult to find information.
Chemistry didn’t make much sense.

6. Dmitri Mendeleev Russian chemist.
Published the first recognized Periodic Table in 1869.
Considered the creator of the periodic table.

7. The Periodic Table:
The Periodic Table is organized much like a grocery store!
It is divided into rows and columns.
All the elements in each row share something in common, while the same is true for each column!
Thank you Dimitri Mendeleev!

8. Periodic Table of Elements
Elements are organized by their physical and chemical properties.

9. Take a look at your Periodic Table
Take a look at your Periodic Table. Where do you think the metals, nonmetals, and metalloids are located?
I have students look at the names of elements to figure this out. Students will likely identify that iron, gold, silver, etc are metals and that they are on the left. Oxygen, nitrogen, neon students will realize are nonmetals and are located on the right.

10. Color in all of the metalloids redB Si Ge As Sb Te At

11. Border all of the nonmetals yellow

12. Border all of the metals blue

13. Why does it make sense that the Metalloids separate the metals and the nonmetals?
Metalloids have physical properties of both metals and nonmetals so they are in between them.

14. The Metalloid Staircase
The 7 metalloids create a “staircase”.
They separate the metals and the nonmetals because they have physical properties of both!

15. Metals and Nonmetals Metals
Metals are located to the left of the metalloid staircase.
Nonmetals are located to the right of the metalloid staircase (except for Hydrogen).
Nonmetals
Metals

16. Gluing in our Periodic Tables into our Interactive Notebooks.

17. The Periodic Table
The elements are put in rows by increasing ATOMIC NUMBER!! 2
Atomic Number He
Atomic Symbol
Atomic Mass
4.00

18. The Periodic Table
Each row is called a “period”.
There are 7 periods.

19. Tell your partner the name of an element in Period 3.

20. How about Period 5?

21. The Periodic Table
Each column in the Periodic Table is called a “group”.
There are 18 groups.
Each group has similar properties!

22. Silently raise your hand to give an example of an element in GROUP 4.

23. What is the element that is in Period 2, Group 7?

24. What about an element in GROUP 16?

25. Periodic Table Scavenger Hunt!
