Question

Jason makes a graphic organizer for insulators and conductors and wants to add the following labels to it.

Label 1: Lacks free electrons
Label 2: Aluminum

In which regions should Jason place each label?

A) Label 1: X
Label 2: Y
B) Label 1: Z
Label 2: X
C) Label 1: X
Label 2: Z
D) Label 1: Z
Label 2: Z

Answer 1

Jason should place the regions in:

C) Label 1: X

Label 2: Z

Answer 2

Answer: C) Label 1: X

Label 2: Z

Step-by-step explanation: Conductors are those substances which conduct electrical current easily because of the presence of free electrons whereas Insulators do not conduct electrical current as they do not contain free electrons. Some common examples of conductors are copper, aluminum, gold, and silver. Some common examples of insulators are glass, air, plastic, rubber, and wood.

Label 1: Lacks free electrons must be placed in the area marked X as they correspond to insulators.

Label 2: Aluminum is an example of conductor and thus must be labelled in area marked by Z.

Area Y corresponds to semiconductors which have properties intermediate to conductors and insulators.
