This document discusses the properties and uses of metals. It defines metals as solid materials that are typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity. It describes key physical properties of metals like shininess, malleability, ductility, and conductivity. Examples are given of gold and copper being made into thin sheets and wires due to their malleability and ductility. Common uses of gold, copper, and aluminum are also listed.

4.  What is a metal ?
A solid material that is typically
hard, shiny, malleable, fusible,
and ductile, with good electrical
and thermal 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.

9. METALLIC LUSTER
The surface newly formed when metals are cut, has a shiny appearance.

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

12. COPPER:
 Electrical wires as it is a
good conductor.
 Water pipes due to its
low reactivity.

13. ALUMINIUM
o Suitable for vessels and bodies of planes etc
