Let’s start all about Physical Properties of Metals and Nonmetals
Physical Properties of Metals and Nonmetals
Physical properties of Metal
- Metals occur in the solid state. All metals are solid except with an exception for mercury which is in the liquid state in its natural form.
- Metals are malleable. Gold and Silver are the best malleable metals.
Malleability: The ability of a metal due to which it can be beaten into sheets is called malleability. For example, Iron, copper, zinc aluminum, etc are malleable metals.
- Metals are ductile. Gold and Silver are the most ductile metals. Copper and aluminum metals are also very ductile and can be drawn into thin copper wire and aluminum wires.
Ductility: The property which allows the metals to be drawn into thin wires is called ductility.
- Metals are good conductors of heat. Silver metal is the best conductor of heat.
- Metals are good conductors of electricity. Silver metal is the best conductor of electricity. The electric wires are made of copper and aluminum metals because they are very good conductors of electricity.
- Metals are lustrous. Gold, silver, and copper are the best lustrous metal.
Metallic luster: The property of metal of shining surface is called metallic luster.
- Metals are generally hard except sodium and potassium are soft metals that can be easily cut with a knife.
- Metals are strong except sodium (Na) and potassium (K) metals which are not strong.
- Metals are high melting points and boiling points except for sodium and potassium metals which have low melting and boiling points.
- The melting point of iron is 1535
- Metals have high densities except sodium (Na) and potassium (K) metals which have low densities
- Metals are sonorous.
Sonority or Sonorousness: The property of metals of being sonorous is called sonority.
The physical property of non-metals
- Nonmetals are neither malleable nor ductile.
- Non-metals do not conduct heat and electricity.
- Non-metals are not lustrous except Iodine is a non-metal having a lustrous appearance.
- Non-metals are generally soft except diamonds which are hard.
- Non-metals are not strong.
- Non-metals have low melting points and boiling points except diamond which is non-metal having high melting and boiling point.
- Non-metals are non-sonorous.
