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

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.

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

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

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.

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

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!

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

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.

Border all of the nonmetals yellow

Border all of the metals blue

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.

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

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

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

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

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

How about Period 5?

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

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

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

What about an element in GROUP 16?
