Cerium was discovered by Jöns Jacob Berzelius and Wilhelm von Hisinger, Swedish chemists, and independently by Martin Heinrich Klaproth, a German chemist, in 1803. Curium is called a transuranium element because it follows uranium on the periodic table. The atomic number of Curium is 96. (Pierre and Marie Curie) Although curium follows americium in the periodic system, it was actually known before americium and was the third transuranium element to be discovered. It is a dense, silver metal in the actinide series that glows purple in the dark.It is named for Marie and Pierre Curie – pioneers in radioactivity research. Can we integrate new capabilities with our existing data architecture? An alpha particle is the equivalent of a helium atom's nucleus. Curium derived its name from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium Curium is very radioactive, more electropositive than Aluminum, chenically reactive.
