Metals exhibit several distinctive characteristics that set them apart from nonmetals and metalloids. Being shiny is one hallmark of metals; this luster makes them desirable in certain applications, such as jewelry and electronics. Malleability refers to the ability of metals to be hammered or pressed into shapes without breaking, which is crucial for manufacturing processes. Ductility is the ability of metals to be drawn into wires, making them versatile for electrical applications. Additionally, metals are known for their excellent conductivity of heat and electricity, allowing them to efficiently transmit energy.

These properties arise from the metallic bonding structure, where positively charged metal ions are surrounded by a "sea" of delocalized electrons, which facilitate these behaviors. This combination of characteristics is why metals are commonly used in construction, electrical wiring, and various manufacturing processes.
