Lesson 2

             Learning Intentions: 

What? predict the chemical and physical properties of elements. 

Why? To better understand how elements are similar. 

Success Criteria:  I can: 

Locate: 

- metals - nonmetals- metalloids on the PT 

Identify: 

- the properties of Metals - Nonmetals - Metalloids

 How can we predict the chemical and physical properties of an element?

Metals - Metalloids - Nonmetals

How does the element Break? 

Malleable - can be hammered into sheets.

Ductile:  Can be drawn into a wire.

Brittle:  Can shatter easily.

Is the element a good conductor? 

Allows electricity to flow through it

What is the element's Luster? 

How it reflects light. 

Metallic (shiny)    OR  

 Non Metallic (Dull)

How reactive is the element?   

Are there signs of a chemical reaction.

I would highly advise you NOT to write anything yet. 

You will do more research!

Metalloids

majority of elements

Separate the metals & nonmetals on the PT

Share properties of metals & nonmetals.

Located to the left of the Metalloids.

Located to the right of the Metalloids.

Hydrogen

Solid at room temperature.

Gas at room temperature.

Shiny, bendable, can be drawn into wires. 

Good conductors of heat & electricity

NOT good conductors of heat & electricity

Break easily

Finish the Lab 

1. At this point, use what you have learned in the lesson, your observations, and data to complete the back of your Lab Sheet. 

2. Turn your lab sheet in to the correct Block Basket.
