Metals and non-metals in the periodic table
The periodic table is a list of all the known elements which are arranged according to the similarities in their properties.
Non-metals are mostly on the right.
Metals are on the left and in the centre.
What type of elements are between metals and non-metals?

Which side are the
metals on?
Metalloids sometimes behave like metals and
sometimes like non-metals.
Metals are on the left and in

Properties of Metals
• You are going to be testing a series of metals to find out what properties a metal has.
• Copy and complete the following table:
Name of Metal
Is it shiny or dull?
Can you bend it?
Does it conductElectricity?
Does if feel cold?
Can you stretch it? Melting point? High or low

Conclusion
• Look at your results. What do all the metals have in common?
• The things they have in common are called their ‘properties’
• What do you think the properties of the non-metals are?

What are the properties of metals?
Properties of metals strongdense
Shiny (lustrous) malleable (easy to bend)
high melting point
sonorous(makes a sound)
high boiling pointductile
(can be streched into wires)
good conductor of electricity
good conductor of heat
Do all metals have these properties?
solid
