Select ALL of the properties of metals.

Select ALL of the properties of nonmetals.

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 temperature-

sulfur is mallable and aluminum conducts electricity. 

chlorine is malleable and conducts electricity. 

aluminum is malleable and conducts electricity.

all three elements are malleable and conduct electricity.
