Einsteinium , the 99th ingredient on the Periodic Table of Elements , is a synthetic chemical element that is grow in passing small amounts and with a very short lifetime . If the name seems familiar , it ’s because it is indeed diagnose after famed physicist Albert Einstein , although he had nothing to do with the factor ’s find or research .
History
Einsteinium was see during the examination of debris from the first atomic number 1 bomb test in November 1952 , according toChemicool . A team of scientist from theLawrence Berkeley National Laboratory , theArgonne National Laboratoryand theLos Alamos Scientific Laboratoryand led by Albert Ghiorso , an American atomic scientist at Berkeley , study the rubble collected by drone using chemical substance analysis . Minuscule sum of einsteinium-253 , an isotope of Es , were light upon ( less than 200 atoms , according to an article printed inNature Chemistryby Joanne Redfern , a British science writer , in 2016).Fermium , the hundredth element , was also discover in the debris .
The results of the test were not print until 1955 , harmonise toPeter van der Krogt , a Dutch historian . At the time of the atomic number 1 bomb calorimeter demonstration , tensions due to the Cold War were running high and many new find were kept confidential . Due to the method acting of creation and the nature of the new elements , further research of einsteinium retain in silence , harmonise to theLos Alamos National Laboratory .
Further production and research on Es , as well as fermium , was done at theOak Ridge National Laboratoryin Tennessee , allot toLenntech . The scientists create larger amounts of the element and also develop methods of purify the atomic number 99 , as draw in a1978 paperby D.E. Ferguson and pose at a symposium . The newspaper publisher distinguish the production of Es and atomic number 100 in atomic reactors by bombard heavy constituent such asuraniumandcuriumwith neutrons and having those products undergo radioactive decomposition . Einsteinium and the other heavy constituent were then extracted from a tank filled with a solution .

Just the facts
Who knew?
Current research
There is very little research involving E . According to Redfern , the chief use of einsteinium is to produce heavy element , including mendelevium . Due to the high rate of disintegration and radioactive nature , there are presently no other function for E .
