Description
Standard State: Presumably a solid at 298 K
Color: Unknown, but probably metallic and silvery white or gray in appearance
Element 116 was identified as a decomposition product of element 118 in experiments
conducted at at The Lawrence Berkeley National Laboratory, Berkeley, The University of
California, and Oregon State University, Corvallis. It is very short-lived and decomposes
into element 114.
Elements 118 and 116 were identified by accelerating a beam of krypton-86 (8636Kr)
ions to an energy of 449 million electron volts and directing the beam onto targets of
lead-208 (20882Pb). After 11 days work, just three atoms of the new
element were identified. The production rates for element 118 are approximately one in
every 1012 interactions. |
