Iron is classified as a metal. It is a member of the transition metals group in the periodic table. Metals are characterized by their conductive properties, malleability, ductility, and a shiny appearance, all of which iron possesses.
Iron is known for its strength and has been used for centuries in construction and manufacturing. Unlike nonmetals, which usually lack luster and are poor conductors of heat and electricity, iron is a good conductor and can be easily shaped into various forms.
Metalloids, on the other hand, exhibit properties intermediate between metals and nonmetals. While iron does not fit into this category, it stands out as a classic example of a metal due to its characteristics and uses.
