CLASSIFYING ELEMENTS BY PHYSICAL PROPERTIES | |
Date: ____________ Name: ___________________________
Purpose: To classify some elements according to some of their physical
properties.
Materials: elements ( aluminum, carbon, copper, iron, lead, magnesium,
nickel, silicon, sulphur, zinc ), magnets, conductivity apparatus
Procedure:
1. Examine the elements located around the room and complete the
charts below based on the properties listed in each chart.
Observations:

Discussion:
1. List the elements that are lustrous, malleable and
conduct electricity. (all three characteristics)
2. List the elements that are NOT lustrous, NOT malleable
and DO NOT conduct electricity.
(all three characteristics)
3. The elements listed in question one are considered
metals, the elements listed in question two are
considered non-metals. Which group would you place
silicon? Why?
4. Could you distinguish between metals and non-metals
based on colour alone? Why?
5. Could you distinguish between metals and non-metals
based on magnetism alone? Why?
