Metals

What is a metal?

• typically solid, shiny, malleable, and good conductors of heat and electricity.

• have properties of both metal and nonmetals; sometimes referred to as semiconductors

• Elements typically not shiny, usually a gas or brittle solid, not malleable, and poor conductors of heat and electricity.

What is malleability?

• material able to conduct heat & electricity

• metals ability to be shaped or formed by hammering or pressure; can be beaten into thin sheets

• the way an object’s surface reflects light

What is luster?

• metals ability to be shaped or formed by hammering or pressure; can be beaten into thin sheets

• the way an object’s surface reflects light

• can be drawn into a wire

What is ductility?

• can be drawn into wire

• metals ability to be shaped or formed by hammering or pressure; can be beaten into thin sheets

• the way an object’s surface reflects light

One of the properties that makes Copper, Cu, useful for household wiring is its ability to conduct electricity well. ​ (a)   could also successfully be strung into a wire and conduct electricity in the form of wire.

• Gold (Au)

• Radon (Rn)

• Bromine (Br)

• Nitrogen (N)

Metals are/have: ​ (a)   (are they shiny or dull?) , ​ (b)   (this means you can make wires) , ​ (c)   (you can change its shape) ,​ (d)   (hard or easy to melt?), ​ (e)   (do we use it for electricity?)

• shiny
• ductile
• malleable
• high melting point
• good conductor of electricity
• soft
• easy to melt
• liquid

Metals are also ​ (a)   . This means they can be hammered or rolled into thin sheets.

• malleable

• brittle
