Transcript of My Favourite Element: Curium

By: Avideh Afshar SNC ID8 Discovery Curium, What is it? Classification Isolation Applications Interesting Facts Electronic Structure Bibliography Curium is a radioactive metallic element; synthetically produced by fusing plutonium with helium ions. My Favorite Element: Curium -The only element that is purple in its solid form
-Boling point is lower than its sublimation point
-Only radioactive when liquid
-Mined underwater The electron configuration of Curium is [Rn] 5f7 6D1 7s2. Curium has 96 positive charged protons and 151 negative charged nuetrons. to blanace out the protons curium also has 97 negative charged electrons. curuim has a total of 7 orbital shells and is made of the next closet gass raidon. Curium has 10 more electrons then raidon. Discovered by Glen T. Seaborg, Ralph A. James and Albert Ghiorso
First intentionally made in 1944 in University of California Berkley
Kept secret by the Glen T. Seaborg committee until 1945
Credit given to Seaborg for discovery
Element named after Marie* and Pierre Curie
* Marie Curie is the only person to win a Nobel prize in two different science fields (chemistry physics)
Curuim has many uses such as in pacemakers, remot navigational buyos and is used for space missions Melting point: 1340 C Boiling Point: 3100 C
Atomic weight: 247 Atomic volume: 18.28 cm3
Group: Actinides Number of Isotopes : 0
Source: Synthetic Radioactive

because Curium is a synthetic element there is no way to isolate it from other raw materials becasue it is man made. http://player.discoveryeducation.com/index.cfm?guidAssetId=F4DD56D9-A3AC-40FA-8ED4-E70BE7E01048&blnFromSearch=1&productcode=DSC http://www.thefreeresource.com/curium-cm-fun-facts-and-information-about-the-element http://en.wikipedia.org/wiki/Curium
