Final answer:
Manganese, exhibiting properties like being a good conductor of electricity, having a shiny lustre, and being malleable and ductile, is classified as a metal, a characteristic property of which is conductivity.
Step-by-step explanation:
Manganese is known to be a good conductor of electricity, which indicates it is a metal. Metals are characterized by their ability to conduct electricity and heat, and they typically also have a shiny metallic lustre, are malleable, and ductile. Manganese not only excels in electricity conduction but also demonstrates these typical metallic properties, making it useful in various applications such as electrical conducting wires and fortifying alloys.
