1. BELL WORK: PAST A S T P E R C U
Using only the following letters, write down as many words as you can. You can only use each letter once per word. You do not have to use each letter per word. It’s a competition so….shhhhh!
A S T P E R C U
EXAMPLE:
STEP
PAST

2. Instead of 26 letters to make words, we have this to make EVERYTHING!

4. CLASSIFYING ELEMENTS
Chapter 9
Elements are pure substances, meaning it can’t be simplified.
Elements are made from only one type of atom.
Example: Carbon is only made from carbon atoms. Hydrogen is only made from hydrogen atoms.
Water is made from hydrogen and oxygen atoms so water is not an element.
(It’s a compound.)

5. Atoms of a specific element are the same no matter where they’re found.

6. Elements have properties.
EXAMPLES: color, shininess, boiling point, melting point, density, flammability, malleability, ductility…

7. Classifying Elements
Elements are classified (grouped together) based on their similar properties.
Metals—shiny; conducts heat and electricity well, malleable, ductile
Nonmetals—the solids are dull and brittle; conducts heat and electricity poorly
Metalloids (or semi-conductors)—have properties of both metals and nonmetals

8. Metalloid Now try this…
You find a substance that is very shiny, somewhat malleable, but not a good conductor of heat and electricity. Can you predict what category of elements it would fall into?
Metalloid

9. It would flatten because metals are malleable.
Now try this…
Your teacher gives you a piece of “metal” and a hammer. After hitting the “metal” with the hammer over and over, what would your outcome be?
It would flatten because metals are malleable.
