metal
property of metals and alloys that allows them to be hammered or rolled into thin sheets
malleable
property of metals in alloys that allow them to be drawn into wires
ductile
occurs because of electrons move freely among a medals, positively charged ions, explains properties, such as ductility to the ability to conduct electricity
