1. NEW UNIT: Elements and the Periodic Table
Can you find the periodic table in this room?
What do you already know?
6.1: A Table of the Elements
Now let’s learn a bit more about this....

2. Elements The periodic table is a table of elements
ELEMENT: a pure substance that cannot be broken down
Think of a block of Lego....
(bring a block of lego!!!!)
You cannot break the one piece of Lego into anything simpler than it already is
You also cannot break an ELEMENT into anything simpler, no matter what physical or chemical means you try
They are the building blocks of all substances

3. Element Symbol How do we represent an element on the periodic table?
ELEMENT SYMBOL: an abbreviation for a chemical element
Example: look at the first element...
Hydrogen is abbreviated as “H”

4. Compounds These are not on the periodic table
COMPOUND: a pure substance made up of two or more different elements
The elements are chemically joined
Example: Water!
Water is not on the periodic table
It is made up of hydrogen and oxygen, so is a compound of these elements
Think of 2 or more Lego blocks put together...you can take them apart
Can only combine certain elements

5. Metals Some elements are metallic, some are not
METAL: a lustrous, malleable, ductile element that conducts heat and electricity
Lustrous= shiny
Malleable= flexible
Ductile= can moulded or shaped (into wire)
Generally on left and center of periodic table!
Examples: pots and pans (easy to shape, heat up), gold, silver (decorative, jewellery), copper (electrical wires)

6. Non-metals
NON-METAL: element that does not conduct heat or electricity
Usually a gas or dull, powdery solid
Dull, brittle, shatters if pounded or stretched, and poor conductors of heat and electricity
Found in upper right portion of periodic table
The line on the periodic that looks like a staircase separates the metals and non- metals...can you find it?
Examples: oxygen, hydrogen, nitrogen (gases), charcoal brick (made of carbon)

7. Metalloids
Elements that are located along the staircase line we just found
METALLOID: an element that has properties of metals and non-metals

8. Let’s see if we understand
Try these questions for homework:
Pg. 215 # 3, 4, 5
It’s time for an experiment!!!
Can you be a metal detective? Let’s see!
