Malleability

Metals are malleable, that is, they can be broken down into thin sheets without breaking. 

  • Example : Aluminium, Iron
  • Exceptions : Zinc, Arsenic, Mercury

Ductility 

Metals are ductile, that is, they can be stretched to make thin wires without breaking.

  • Example : Copper, Aluminium
  • Exceptions : Mercury, Zinc 

Luster (or Shine)

All metals have a shiny surface. They are lustrous. Though, they can lose their luster by getting corroded  

  • Example : Copper, Aluminium, Gold
  • Exceptions : No- exceptions

Heat Conductivity

Metals are good conductors of heat, that is why frying pans are made of metals.

  • Example : Silver, Copper
  • Exceptions : Mercury, Lead

 

Electrical Conductivity

Metals are good conductors of heat, that is why they are used to make electrical wires

  • Example : Silver, Copper
  • Exceptions : Mercury, Lead

 

Hardness

Most metals are hard . This hardness varies from metal to metal.

  • Example : Aluminium, Iron
  • Exceptions : Sodium, Potassium

Solids 

Metals are solid at room temperature.  

  • Example : Aluminium, Iron
  • Exceptions : Mercury

Melting and Boiling points

Metals have high melting and boiling points . (>1000°C)

  • Example : Tungsten, Gold, Silver, Copper
  • Exceptions : Sodium, Potassium, Mercury, Gallium, Cesium 



Sonority

Metals are sonorous. They make sounds when hit. 

  • Example : Tin, Silver, Gold, Copper, Iron
  • Exceptions : Mercury
