What property of nonmetals is the opposite of malleable and ductile?
Brittle is the property of the non metal which says them to be non malleable and non ductile.
Non metals may be in gaseous or liquid state. They thus are not so
hard i.e. they are brittle where they
=>cannot be drawn into wires i.e.ductility
=>cannot be spread in sheets i.e. malleability.
