This power point about how the elements classified talk about the elements with easy explanation and able to be understood

1. How the elements
classified?
Made by: Donia Mamdouh

2. Elements
Metals
Non-Metals
Metalloids
How we
classify it

3. • Compare contrast: metals non metals and
metalloids

4. How we differentiate between
the elements
• To differentiate between the three
kinds of the elements we must measure:

5. Malleability
• Malleability is characteristic of
usually metals
• It is the ability of a solid to bend
or be hammered into other shapes
without breaking. Examples of
malleable metals are gold, iron,
aluminum, copper, and lead.

6. Ductility
• Ductility is a characteristic of a metal
where it is capable of sustaining large
permanent changes in shape without
breaking. An example is when a piece
of metal is drawn into a wire. It is
characterized by the internal
structure of the material flowing
under shear stress.

7. Luster(shine)
• Luster is a description of the way
light interacts with the surface
of a crystal, rock, or mineral.
For example, a diamond has an
adamantine

8. Electrical conductivity
Electrical conductivity, a measure of a metal's
ability to conduct an electric current

9. Thermal conductivity
• Thermal conductivity, the
intensive property of a metal
that indicates its ability to
conduct heat

10. Metals
• Describe
• What is the characteristics of
metal that you see in the picture?

11. Non-metals
• Think
• Why the sulfur is non-metal?

12. Metalloids
• Except:
• According to the picture, do you think that
silicon has in it metallic or non-metallic
properties
