Lesson 2
Slide 1 - Diapositive
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
Slide 2 - Diapositive
How can we predict the chemical and physical properties of an element?
Slide 3 - Diapositive
Metals - Metalloids - Nonmetals
Slide 4 - Diapositive
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.

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
Slide 17 - Question de remorquage
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.
