Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Metals

Metals are a category of elements characterized by their shiny appearance and ability to conduct heat and electricity. They typically have high melting and boiling points, and they are malleable and ductile, allowing them to be shaped into various forms. Common examples include iron, copper, and aluminum.

Conductivity

Conductivity refers to the ability of a material to allow the flow of electric current or heat. In metals, free-moving electrons facilitate this process, making them excellent conductors. This property is essential in various applications, including electrical wiring and heat exchangers.

Physical Properties of Elements

Physical properties are characteristics that can be observed or measured without changing the substance's chemical identity. For metals, these properties include luster (shininess), malleability, ductility, and conductivity. Understanding these properties helps in identifying and classifying elements in the periodic table.
