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

the centre.

Non-metals are mostly

on the right.

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
