Classifying the Elements
Part B: Metal, Non-metal OR Semi-metal?
Use the information from the worksheet ‘Physical Properties of Elements’ to help you classify the
following elements as either a metal, semi-metal or non-metal.
E
L
P
a) Element A is lustrous and silvery with a high electrical conductivity.
b) Element B has a low melting point and shatters into small crystals when hammered.
c) Element C can be drawn into wires easily.
d) Element D is a gas at 25oC
e) Element E is a semi-conductor and has a very high melting point.
f) Element F has a high thermal conductivity and is highly malleable.
Fort each element below, examine the properties and decide if it is
a metal, non-metal or semi-metal.
