2. To know how the periodic table is divided into metal and non- metals
Learning Outcomes1. To be able to
describe the properties of metals and non-metals
2. To be able to show on the periodic table where metals are and where non-metals are

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?
Xe

What aremetalloids?
Which side are the non-metals on?
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.
