Why Are Metals Malleable and Ductile? | Reference.com

The sliding of atoms when force is applied is the reason that metals can change their shapes. Since all things are made of atoms, including metal, the atoms must be moved in order to change the shape of the metal. Whether a metal is malleable, ductile or both, most metals are able to be changed with the use of force because their atoms are movable.
