Metal vs non-metal

metalsMetals are found on the _____________ of the

periodic table.There are __________ metals than non-metalsCommon properties of metals include:

Malleable: this means they can be bent and bashed into shape

Ductile: this means they can be drawn out into thin wires

Conductors: this means they allow heat and electricity to travel along them

Shiney: they are reflective of lightUsually grey: most metals are a grey colourSolid at room temperature: except mercury (liquid)

Non-metalsCommon properties of non-metals include:

Brittle: this means they break easily if hitVarious colours: non-metals come in many

coloursInsulators: most non-metals are non-

conductors, an exception is graphite (C), it is an excellent conductor of electricity.

Solids, liquids and gases: non-metals come in all different states. Bromine (Br) is the only naturally occurring liquid non-metal.

EncartaAnswer each one as you go, we will do this as a

class by looking up the information together1. What are the physical properties of metals? 2. Which elements are considered to have both

metal and non-metal properties? these are also known as semi-metals.

3. What are some of the chemical properties/reactions of metals (list at least 3 different reactions)?

4. Type in the word non-metals: What are some of the properties of non-metals?
