physical properties. Which student correctly classified an element
based on its physical properties? (6.6A & 6.3A)
A.
B.
C.
D.
Student A- Sodium is a nonmetal because it has a high
conductivity, is not malleable, and lacks luster.
Student B- Argon is a metal because it has a high
conductivity, is malleable, and has a shiny luster.
Student C- Iron is a metalloid because it has a high
conductivity, is malleable, and has a shiny luster.
Student D- Silicon is a metalloid because it has
moderate conductivity, is not malleable, and has a
shiny luster.
15. Groups of students completed an investigation in which they
compared a sample of copper to a sample of carbon. Students
performed a series of tests on each sample and recorded
observations. Their observations are recorded below:
Hammer Test
Appearance
Ductile
Conductivity
Copper
Sample became thinner
and wider when hit
repeatedly with a hammer
Shiny
Wire sample shows that
copper is ductile
Wire sample was able to
complete a circuit and turn
on a light bulb
Carbon
Sample is brittle and
crumbles when hit with a
hammer
Black and dull
No wire sample (brittle
means not ductile)

circuit did not result in
turning on a light bulb
