Word Origin and History for malleable Expand. adj. late 14c., capable of being shaped by hammering, from Middle French malleable and directly from Medieval Latin malleabilis, from malleare to beat with a hammer, from Latin malleus hammer (see mallet). Figurative sense, of persons, capable of being adapted first recorded 1610s.
This is different from ionic bonding (where no electrons are shared at all) and covalent bonding (where the bonds exist only between two atoms). A metal that you can hammer into thin sheets is malleable. Gold, silver, aluminum, iron, and copper are malleable. Non-malleable metals such as tin will break apart when struck by a hammer. A metal behaves as an array of metal ions or kernels immersed in a âseaâ of mobile valence electrons. Metallic bonds consist of the attractions of the ions to the surrounding electrons.
