Some metals are m________ , which means the can be hammered into different shapes.

Some metals are d_______, which means they can be drawn into a wire.

If an element is lustrous and malleable, it is most likely to be a _________.

Mark the properties shared by metals.​ ​ (a)   ​ (b)   ​ (c)   ​ (d)   ​ ​ (e)  

• luster

• bad conductor of heat

• good conductor of heat

• malleable

• ductile

• bad conductor of electricity

• good conductor of electricity

What property of metals allows them to be drawn into wires?

• Malleability

• Ductility

• Brittleness

• Opacity

Answer explanation

Metals can be drawn into wires due to their property of ductility, which allows them to be stretched into thin wires without breaking.

Which of the following is a property of metals?

• High melting point

• Low density

• Poor conductor of heat

• Insoluble in water

Answer explanation

The property of metals that is described as having a high melting point is the correct choice.

Elements that have luster, are good conductors of heat and electricity, and are ductile and malleable.

• Metal

• Metalloid

• Non-Metal

Answer explanation

Elements that have luster, are good conductors of heat and electricity, and are ductile and malleable are classified as metals.
