Einsteinium ( /aɪnˈstaɪniəm/ eyen-STY-nee-əm) is a synthetic element with the symbol Es and atomic number 99. It is the seventh transuranic element, and an actinide.
Einsteinium was discovered in the debris of the first hydrogen bomb explosion in 1952, and named after Albert Einstein. Its most common isotope einsteinium-253 is produced in a few dedicated high-power nuclear reactors with a total yield on the order of one milligram per year. The re...

Einsteinium ( /aɪnˈstaɪniəm/ eyen-STY-nee-əm) is a synthetic element with the symbol Es and atomic number 99. It is the seventh transuranic element, and an actinide.
Einsteinium was discovered in the debris of the first hydrogen bomb explosion in 1952, and named after Albert Einstein. Its most common isotope einsteinium-253 is produced in a few dedicated high-power nuclear reactors with a total yield on the order of one milligram per year. The reactor synthesis is followed by a complex procedure of separating einsteinium from other actinides and products of their decay. Other, heavier isotopes are synthesized in various laboratories, but at much smaller amounts, by bombarding heavy actinide elements with light ions. Owing to the small amounts of produced einsteinium and its short half-life, there are currently almost no practical applications for it outside of basic scientific research. In particular, einsteinium was used to synthesize, for the first time, 17 atoms of the new element...
