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?
