4. What is a metal ?
A solid material that is typically
hard, shiny, malleable, fusible,
and ductile, with good electrical
and thermal conductivity
PROPERTIES OF METALS
5. The physical properties of
metals include shininess,
malleability, ductility, and
conductivity.
.
Physical Properties
6. For example, gold can be made into thin sheets or other shapes
A malleable material is one that can be hammered or
rolled into flat sheets and other shapes.
7. For example, copper can be made into thin wire
A ductile material is one that can be pulled
out, or drawn, into a long wire.
8. Conductivity is the ability of an object to
transfer heat or electricity to another object.
10. Most metals are good conductors.
In addition, a few metals are magnetic.
For example, iron (Fe), cobalt (Co), and nickel (Ni) .
Most metals are also solids at room temperature.
However, one metal—mercury (Hg)—is a liquid at
room temperature
11. Some of the Uses:
GOLD :
Electrical connections on circuit boards - due
to its conductivity
Jewellery - due to its lack of reactivity
