Can an element eventually become another element? Radon is produced when the element radium slowly decays. The element was discovered by Ernest Rutherford and Robert B. Owens. Radon is a colourless and odourless gas; however, it is dangerous because it gives off radiation. Some spas in Japan and Austria specialize in radon bathing, which supposedly makes people feel young and energetic again. It is represented as Rn, and its atomic number is 86.
Francium is named after the country of France. Francium was discovered by Marguerite Perey, a French chemist. It is an intensely radioactive element. It is one of the rarest elements in nature. Francium’s atomic number is 87, and it is represented as Fr.
Radium is a silvery white metal that quickly reacts with nitrogen in the air. The name of the element comes from the Latin word radius, meaning ‘ray’, as radium glows faintly in the dark. It is a poisonous, heavy, and radioactive metal. The element was discovered by Marie Curie and Pierre Curie. It has the atomic number 88, and is represented as Ra.
