Curium , including Technical Data, Safety Data and its High Purity propertiesresearch, applications and other useful facts are discussed below. Scientific facts such as the atomic structure,ionization energyabundance on Earthconductivity and thermal properties are included. 

Curium is a Block P, Group 3, Period 7 element. The number of electrons in each of Curium‘s shells is 2, 8, 18, 32, 25, 9, 2 and its electronic configuration is [Rn] 5f7 6d1 7s2. In its elemental form curium‘s CAS number is 7440-51-9. The curium atom has a radius of and it‘s Van der Waals radius is Curium is radioactive. 

Curium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors. Curium is found in spent nuclear fuel and small amounts are produced for research. Curium was discovered by Glenn T. Seaborg, Ralph A. James and Albert Ghiorso  in 1944. The element was named in honor of Marie and Pierre Curie. 
Curium Safety Data. The safety data for curium metalnanoparticles and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the left margin. Curium compounds have no biological role.
