Lesson 11

Classifying Elements
Click next to this if you want to learn a little about the periodic table (I know we haven't started it yet but... it should be fun anyway)

Lab Investigation:

Our lab investigation today helped us understand some of the physical properties of matter.

Incase you had a hard time copying down today's notes here they are... your welcome!!!

Classifying Elements: Lab Investigation Lesson 10

Topic: Lab: Classifying Elements

Materials Needed: Lab kit for classifying elements

Lesson:
1. Take up homework – pg. 47 # 1-4
2. Read page 48 with class (review lab)
3. Must hand in labs by Monday and Quiz is on Monday (particle theory of matter – states of matter and classifying elements)
4. Complete Lab - Homework – pg. 49 #1-2
5. Upcoming – worksheet on Metals (pg. 50) and testing for elements worksheet.

Note:

Classifying Elements

Elements can be sorted into various groups according to similarities between various elements.

In our lab investigation you discovered different Elements have different physical properties including:

Colour Lustre Malleability Density Magnetism Electrical Conductivity

These distinctions help us figure out what groups or families each element belongs to.
Pg. 50 Table 1 and 2 Text.
Metals:


Metals all share similar properties:
Conduct Electricity
Are easily magnetized
Malleable
Dense
Solid at room temperature
Silvery/copper/gold colours

Non-metals:
Non-metals also share similar properties:
Brittle
Not very dense
Dull (not much luster)
Insulators (do not conduct electricity)
Not attracted by magnets
Gas or solids at room temperature


Uses for Metals and Non Metals

Make a chart to determine all of the possible uses you can think of for non-metals and metals include at least 10 uses.
