Difference between Metals and Non-metals
Metals |
Non– metals |
Metals are mostly present as solid at room temperature. | Non- metals are mostly present As solid or gases. |
Exceptional case for metal which is not solid at room temperature is gallium and mercury. These are Present as liquid at room temperature. | Exceptional case for Non- metals which is not solid or Gaseous at room temperature is Bromine. |
The melting point of the metals is generally high. | The melting point of non metals are generally low. |
The boiling point of metals are normallyhigh. | The boiling points of the non – Metals are Normally low. |
Exceptional case for the high melting and boiling point of the metals are – gallium and Cesium. | Exceptional case for the low boiling and melting point of non- metals are – graphite and diamond. |
The density of metals are usually high. | The density of non – metals Are generally low. |
Metals have a shiny appearance which is known As lustre. | Non – metals Does not posses lustre. It is Non – lustrous except the Iodine. |
Metals are generally Hard. They have the quality of hardness, strength and toughness. | Non – metals Are generally weak. Yet they are solid but not so hard. These are generally soft. |
Exceptional case for the hardness of the metals are – sodium and potassium. | Exceptional case for the softness of the non metal is diamond. |
Metals are malleable i.e. it has the property that metal can be beaten into a thin sheet. | Non metals are not malleable. It does not has property to drawn into sheets. |
Metals are ductile. I.e. it can be drawn into a thin long wire. For example gold and silver can drawn into an long thin wires. | Non- metals are not ductile. They can not form a thin wire. |
Metals are good conductor of heat . | Non – metals are bad conductor of heat. |
Metals are good conductor of electricity. They are conductors. | Non – metals Are bad conductor of electricity. They are insulators. But the exception is Graphite. |
Metals have property of Producingsonorous sound. | Non – metals Don’t Have the property of Producing sonorous sound. |
Examples of metals – copper, iron, gold, silver etc. | Examples of non metals are –
Graphite, Bromine, Iodine. |
