Element 114

Element 114 is an interesting discovery. It really looks like the theoretical models and hypothesis regarding a stable island of elements around this atomic number now (partly) have been validated. Below you'll find a short excerp from the LA Times incl. many interesting links with issues relating to element 114.

Now Introducing Element 114 To The Periodic Table.
From Los Angeles Times, Thursday, January 28, 1999. pg. B-2

Russian scientists have created element 114 and, true to predictions, it is more stable than those immediately before it in the periodic table, according to a news report in the Jan. 22 Science.

Physicists at the Joint Institute for Nuclear Research in Dubna shot ions of Calcium-48 at plutonium-244 to produce the new element, which has a molecular weight of 289. The new element decays with a half-life of 30 seconds into element 112 which, by contrast, has a half-life of only 28 milliseconds. Element 113 has not been created yet.
