Retake Quiz: Metals, Nonmetals, and Metalloids

The elements argon, krypton, and xenon are all non-metals. What property would these elements have in common?

• Shiny, lustrous surface

• Soft and malleable

• The ability to conduct electrical or thermal energy

• Suitable for being shaped by beating or rolling

What physical properties are used to classify elements as metals, non-metals, or metalloids?

• Color, smell, physical state

• Reactivity, streak, hardness

• Ability to burn, mass, density

• Luster, conductivity, malleability

Which of the following is a property of a non-metal?

• Conducts electricity and heats well

• Can be hammered into thin sheets

• Is brittle and breaks easily

• Has a shiny, metallic luster

All of these properties describe metals EXCEPT-

• malleable

• conductor

• brittle

• shiny

Unlike non-metals, most metals tend to -

• conduct electricity and heat well

• be gases at room temperature

• break easily when hammered

• have less luster and shine

Electrical wires are made from metals such as copper and chromium because -

• wires can be stretched and bent

• most metals have a metallic luster

• electricity flows in a complete circuit

• metals are good conductors of electricity

Why are metals often used in the construction of buildings and bridges?

• Because they are shiny and attractive

• Because they are malleable and ductile

• Because they are brittle and break easily

• Because they are poor conductors of heat and electricity

Which of the following properties is not typically associated with non-metals?

• They are good conductors of electricity

• They are brittle and break easily

• They have a dull appearance

• They are poor conductors of heat and electricity

Why are metals like gold and silver often used in jewelry?

• Because they are brittle and break easily

• Because they are poor conductors of heat and electricity

• Because they are malleable and ductile

• Because they have a dull appearance

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

• TRUE
• FALSE
