Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is named after Albert Einstein and is a member of the actinide series and is the seventh transuranium element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
3 Φεβ 2021 · It was in the fallout from Ivy Mike’s explosion, amid the chemical debris, that atomic number 99 was found for the first time. Only about 200 atoms of this element were detected, which shows just...
3 Φεβ 2021 · Einsteinium is an incredibly scarce, artificial element that decays so quickly that researchers don’t know much about it. Now, using state-of-the-art technology, a team has examined how it...
4 Φεβ 2021 · In their paper, the researchers explain how they managed to use just 200 nanograms of Es-254 (a rare form of einsteinium with a half-life of 275.5 days) to run their experiments. A nanogram is just one billionth of a gram, so these experiments took place on an incredibly small scale.
Einsteinium was discovered in the debris of the first thermonuclear explosion which took place on a Pacific atoll, on 1 November 1952. Fall-out material, gathered from a neighbouring atoll, was sent to Berkeley, California, for analysis.
7 Φεβ 2021 · With 99 protons and 99 electrons, it sits in obscurity near the bottom of the periodic table of chemical elements, between californium and fermium. It first showed up in the explosive debris of...
3 Φεβ 2021 · Like other elements in the actinide series — a group of 15 metallic elements found at the bottom of the periodic table — einsteinium is made by bombarding a target element, in this case...
