Metals, Non-metals and Metalloids
Most of the elements are metals
The remaining are called non-metals
The ones with both metallic and non-metallic characteristics are called metalloids
Metals
Properties
Most of them are strong
Have high melting and boiling points, and density
Good conductors of electricity
Are malleable
Good conductors of heat
Are ductile
Have luster
Are sonorous
Examples
Elements
Copper
Aluminium
Iron
Alloys
Steel
Bronze
Brass
Non-metals
Properties
Weak and brittle
Low melting and boiling points
Poor heat conductors
Some are lighter that air
Insulators
