A student is trying to classify an unidentified, solid gray material as a metal or a nonmetal. Which question will best help the student classify the material?

• Is the material malleable or ductile?

• Does the material feel hard to the touch?

• Will the material float in water?

• Does the material feel rough or smooth?

Which statement does NOT correctly compare silicon with another element?

• Silicon is a better conductor of electricity than sulfur.

• Silicon conducts electricity as well as copper does.

• Silicon is a solid at room temperature, but argon is a gas.

• Silicon is less malleable than silver.

Aluminum, sulfur, and chlorine are elements found on the periodic table. Tests involving these three elements 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

Brianna and Micah are lab partners and were assigned to analyze the difference and physical properties between 4 solid elements. They wrote their findings in their lab manual as displayed below. Based on their findings, Mr. Johnston's exit ticket is asking: Which element is a NONMETAL?

• Element 1

• Element 2

• Element 3

• Element 4
