Metallic appearance of metals: Metals are characterized by their shiny, reflective surface, which is due to their ability to reflect light because of free electrons in their structure, giving them a distinctive "metallic" look (source content).
Good conductors of heat and electricity: Metals possess high electrical and thermal conductivity because their free electrons allow easy transfer of energy, making them efficient conductors (source content).
Pure metals are soft and malleable: In their natural, chemically pure form, metals tend to be soft and easily shaped without breaking, due to their crystalline structure and lack of impurities (source content).
Impurities improve metal strength: The addition of impurities or alloying elements enhances the strength and durability of metals by hindering dislocation movement within the crystal lattice, thus improving their structural properties (source content).
