Metals have several properties including conductivity, malleability, ductility, being solid at room temperature, and having luster. Conductivity refers to the ability of metals to conduct heat and electricity. Malleability refers to their ability to be hammered or pressed into different shapes without breaking. Ductility refers to their ability to be stretched into wires. Metals are solid at room temperature, unlike other elements such as gases or liquids. Finally, metals have luster, meaning they have a shiny appearance when polished.
