All the elements can be divided into three groups:
Properties of Metals:
A non-metal is an element that is neither malleable nor ductile, and does not conduct electricity. The examples of non-metals are Carbon, Sulphur, Phosphorus, etc.
Properties of Non-Metals:
Comparison among the Properties of Metals and Non-Metals:
|Metals are malleable and ductile. They can be hammered into thin sheets
and drawn into thin wires.
|Non-metals are brittle. They are neither malleable nor ductile.|
|Metals are good conductors of heat and electricity.||Non-metals are bad conductors of heat and electricity.
Exception: diamond, graphite
|Metals are lustrous and shiny and can be polished.||
Non-metals are non-lustrous and dull and cannot be polished.
|Metals are solids at room temperature Exception: mercury||Non-metals may be solid, liquid or gases at the room temperature.|
|Metals are strong and tough. They have high tensile strength.||Non-metals are not strong. They have low tensile strength.|
|Metals are sonorous. They make a ringing sound when struck.||6. Non-metals are not sonorous.|
