The diagram above shows the repeating groups of atoms that make up two samples. Will the
properties of the two samples likely be the same or different? (Examples of properties are smell,
color, and the temperature at which a substance melts.)
a
The properties will likely be different because the repeating groups of atoms that make up
each sample are different.
b
The properties will likely be different because there are more repeating groups of atoms in
Sample 2.
c
The properties will likely be the same because the repeating groups of atoms that make up
the two samples have the same number of atoms.
d
The properties will likely be the same because the repeating groups of atoms that make up
the two samples have two of the same types of atoms.
