The nonmetals helium, neon, and argon and the metals copper, silver, and gold are among only a few elements that are found in nature in their pure forms. What can you infer about the chemical reactivity of these elements
A pure element is a pure substance that has only one kind of atoms. If a substance is present in nature in elemental form, it means that the element is not very reactive as reactive elements exist in the form of their compounds with atoms of other elements. Element can be categorized as a metal or a non-metal based on some physical observable properties. Generally, metals are shiny lustrous solids and nonmetals are gases. Metals are good conductors of heat and electricity whereas nonmetals are not conductors.
