Question map
Which one of the following metals has both malleability and ductility properties ?
Explanation
Metals are generally characterized by physical properties such as luster, high thermal and electrical conductivity, malleability, and ductility [3]. Malleability is the ability of a material to be beaten into thin sheets, while ductility is the ability to be drawn into thin wires [2]. While most metals possess these properties to some degree, gold (Au) and silver are recognized as the most malleable and ductile metals [2]. In contrast, sodium (Na) is a soft alkali metal that can be cut with a knife, and mercury (Hg) is an exception to general metal properties as it exists as a liquid at room temperature, making it neither malleable nor ductile in its standard state [4]. Cerium (Ce), a lanthanide, also exhibits these properties but gold is the quintessential example of high malleability and ductility among the given options [3].
