Explanation:

<br/> <b>Toughness</b>: When a huge external force is applied on a metal, the metal will experience fracture. Toughness is the ability of a metal to resist fracture. The ability of a material to resist fracture due to high impact loads, is called toughness. <br/> <br/> <b>Hardness</b>: Hardness is the ability of a metal to resist permanent change of shape caused by an external force. <br/> <br/> <b>Brittleness</b> <br/> Brittleness is a property of material which breaks with little or no deformation. <br/>
