Radium was named for the Latin for a ray and proved to be the most radioactive natural substance ever discovered. The chemical symbol for Cobalt is Co. Cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The description of the element in its natural form. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. It is toxic due to its radioactivity. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. It rarely occurs in its elemental state or as pure ore compounds in the Earth’s crust. 1) You may use almost everything for non-commercial and educational use.
