Properties & Classification of Materials

What is the lustre of a material?

• The refractive index of the material.

• The ability of a material to form thin sheets.

• How the light interacts with the surface of the material.

• The absorption properties of a material.

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

There are more metals than non metals in the periodic table.

• True
• False

What does malleable mean?

• able to be shaped
• will break easily
• can be used for wire
• is shiny

What is the ability of a substance to allow heat, sound, or electricity to flow through it?

• Malleability
• Ductility
• Solubility
• Conductivity

At room temperature, most metals are

• liquid
• solid
• gas
• an alloy

A covalent bond is...

• Transfer of electrons between two atoms
• A electron shared between two atoms
• When two atoms gain energy
• A shared pair of electrons between two atoms

A mixture of two or more metals is called:

• mixture
• solution
• compound
• alloy

The ability of a material to deform, usually by stretching along its length. This property allows us to make wires.

• conductivity
• ductility
• malleability
• hardness

The ability of a material to be shaped in all directions without cracking or breaking.

• hardness
• ductility
• malleability
• conductivity
