Year 8 - Metals and Non-Metals

Metals and Non-Metals

Multiple Choice

What are properties?

• They give us an idea of what the object can do.

• They describe the object.

• They tell us what an object cannot do.

Properties of metals

• Metals have luster. This means they are shiny

• Ductile - can be drawn into wire

• Malleable - can be hammered into sheets

• Metals have a high melting point. They are also very dense.

• Metals are good conductors of electricity and heat

• Metals react with oxygen and water. This results in corrosion and rust

Multiple Choice

What is NOT a property of metals

• brittle

• ductile

• malleable

• conductor

Multiple Choice

What does "malleable" mean?

• Can be made into a shape.

• Brittle

• Ductile

• Shiny

Multiple Choice

What property of metals means that heat and electricity can move easily through?

• luster

• conductor

• malleable

• ductile

Multiple Choice

What is the BEST example of a conductor?

• A wooden block

• A ceramic mug

• A glass cup

• A metal bowl

Multiple Choice

What is a conductor?

• a material that slows the transfer of heat

• a material that transfers heat easily

• a material that is fluffy

• a material that is temperature controlled

Multiple Choice

What does ductile mean?

• electricity flows easily

• quacks like a duck

• can be drawn into a wire

• able to bend

Multiple Choice

At room temperature metals are ____________.

• plasma

• gases

• liquid

• solid

Properties of non-metals

• Non-metals do not have luster; they are dull

• Non-metals are brittle so they break easily. This means non-metals ARE NOT ductile or malleable

• Non-metals have low density

• Have a low melting point

• They are poor conductors (insulators) of heat and electricity

Multiple Choice

Which words best describe NON-METALS?

• ductile, shiny, brittle

• malleable, dull, brittle, ductile

• brittle, dull, insulators

Multiple Choice

Where are the non-metallic elements found in the periodic table?

• In the middle

• In the top rows

• On the left-hand side

• On the right-hand side

Multiple Choice

Non-metals are insulators, this means electricity ______ flow through them.

• can

• cannot

Multiple Choice

Non-Metals generally have ____ boiling points.

• High

• Low

Metalloids (semi-metals)

• Metalloids have properties of both metals and non-metals

• Metalloids are solids that can be shiny or dull

• They conduct electricity and heat better than non-metals but not as well as metals.

• Metalloids are malleable and ductile

Multiple Choice

A student is given a sample of an unknown substance. He is asked to determine if it is classified as a metal, a metalloid, or a nonmetal. He discovered that the unknown element conducted some heat and electricity, had a shiny luster, and broke easily. This element is most likely a
