2.1-The Periodic Table (An Overview) - 3

What is a key property of metals?

• Poor conductors of heat

• Good conductors of heat and electricity

• Brittle

• Non-reflective

What does it mean when freshly cut metals reflect light?

• Ductile

• Malleable

• Luster

• Brittle

Metals can be hammered into sheets because they are:

• Brittle

• Conductors

• Malleable

• Non-metallic

Metals can be drawn into wires because they are:

• Ductile

• Brittle

• Reactive

• Magnetic

What is a main property of non-metals?

• Poor conductors of heat and electricity

• Shiny

• Ductile

• Magnetic

How do the properties of non-metals compare to metals?

• The same

• Opposite

• Better

• Identical

Although non-metals, carbon and graphite are:

• Poor conductors

• Not reactive

• Good conductors of electric current

• Insulators

What happens when solid non-metals are hit with a hammer?

• Bend

• Stretch

• Stay the same

• Shatter (they are brittle)

What is a characteristic of metalloids?

• Only metallic properties

• Only non-metallic properties

• Both metallic and non-metallic properties

• Gases at room temperature

The properties of metalloids can be changed by using:

• Electricity

• Lasers

• Mixtures

• Water
