Metallic elements are a group of chemical elements that are characterized by their shiny appearance, good electrical and thermal conductivity, and malleability. They are typically solid at room temperature, with the exception of mercury, which is a liquid. Common examples of metallic elements include iron, copper, and gold. These elements tend to lose electrons easily, forming positive ions. Most metallic elements are found on the left side and in the center of the periodic table. They are often used in various applications, such as construction, electronics, and jewelry. Their unique properties make them essential in industries ranging from manufacturing to technology.
