It means that it can be hammered into different shapes

Lustre means shine

Ductile means that the metals can be rolled into thin, flexible wires without breaking

Metals make a ringing sound when they come into contact

Soft and weak Brittle Poor conductors of heat and electricity Non sonorous Dull Non ductile

Metals are non renewable because they cannot be replaced once they are used up
