To be precise, radium, per se, has not yet been isolated as a metal, but only in the form of salts,—chlorides and bromides. [...] It is supposed that the molecules of radium (composed of similar atoms) during their decomposition into those of the gas helium, are also frittered down into heat and, in part, are liberated as radio-activity.
