Physical Properties of Metals: Malleability and Ductility. The delocalised electrons in the 'sea' of electrons in the metallic bond, enable the metal atoms to roll over each other when a stress is applied

The metallic bond is ductile and malleable because they are not directly bonded with each other.  

Explanation:

Metallic bonds rise from electrostatic metallic forces between electrons and positively charged ions. In a metallic bond, electrons are free to move throughout the metallic structure.  

Metals are malleable as they can be beaten into sheets and ductile because they can be pulled into wires. This happens because atoms share electrons and can move freely throughout the structure.  

Example: Gold is more ductile and malleable when compare to silver and platinum.
