Aluminum, sulfur, and chlorine are elements found on the periodic table. Tests involving these three element would show that at normal room temperature -

• sulfur is malleable and aluminum conducts electricity

• chlorine is malleable and conducts electricity

• aluminum is malleable and conducts electricity

• all three elements are malleable and conduct electricity

Some students conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table below.

Based on these observations, which sample is most likely a nonmetal?

• Sample 1

• Sample 2

• Sample 3

• Sample 4
