Which of these is a property of metals?

• It's malleable
• It can't conduct electricity
• They are used in food
• It's very brittle

Some characteristics of a metal are that it is malleable and ductile.

• TRUE
• FALSE

How would this element be classified?

• Metal
• Nonmetal
• Metalloid
• Metamorphic

If an object breaks easily, that means it is probably-

• malleable
• brittle
• ductile

If an object is a better conductor of heat and electricity than nonmetals, but not as good of a conductor as metals, then it is a-

• semi-conductor
• non-conductor
• good conductor

Which type of elements touch the zigzag line?

• Metals
• Nonmetals
• Metalloids
• Metals and Metalloids

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

• Sample 1
• Sample 2
• Sample 3
• Sample 4

Anytime you see the word SEMICONDUCTOR - what substance do you have?

• Metal
• Nonmetal
• Metalloid

´Elizabeth was examining elements and their physical properties. She described an element is her science journal as having no shine, an insulator, and  very brittle. What would this element be a metal, nonmetal, or metalloid?

• metal 
• nonmetal 
• metalloid
