Unit 1&2 Review

Which correctly lists the three elements from greatest conductivity to least conductivity?

• Metal→Metalloid→Non Metal

• Non Metal→Metal→Metalloid

• Metalloid→Non Metal→Metal

• Metal→Non Metal→Metalloid

All of these properties describe metals EXCEPT —

• malleability

• conductivity

• shiny

• brittle

Conductivity is a physical property of matter that describes its ability to —

• reflect light from its lustrous surface.

• transfer thermal and electrical energy.

• exist in nature as a solid, liquid, or gas.

• be hammered and rolled into thin sheets.

• Reflects light

• Magnetic

Which correctly describes a test that is used to determine a mineral’s identity?

• Use a balance to find the mass of the mineral

• Try to scratch the mineral with an iron nail

• Observe the shape and size of the mineral

• Submerge the mineral in a beaker of water

What are we observing in metals, non metals, and metalloids?

• radioactive properties

• probable properties

• physical properties

• mineral properties

Which one describes ductility?

• ability to be formed under pressure

• ability to reflect light

• ability to be stretched into a wire
