Samarium is a silvery-white metal that has a characteristic glow, it is stable when exposed to air. In the atmosphere, it is relatively ductile, malleable and soft. It forms part of the external transition metals and belongs to the group of lanthanides. It was discovered in 1879 by the French chemist Paul-Emile Lecoq de Boisbaudran who isolated the metal from the mineral Samarsquita, after having been observed through for spectroscopy by Swiss chemical Marignac in didymium. It was named af …
