Einsteinium is a synthetic, silvery, radioactive metal. In the periodic table, it is located to the right of the actinide californium, to the left of the actinide fermium and below the lanthanide holmium with which it shares many similarities in physical and chemical properties.
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.
3 Φεβ 2021 · Explosive findings. 300 micrograms of einsteinium. Einsteinium (Es) is the 99th element in the periodic table. It was first discovered in 1952 when a thermonuclear device dubbed “Ivy...
In some ways, einsteinium behaves similarly to its lighter neighbours on the periodic table, taking on a +3 oxidation state in a complex with an octadentate hydroxypyridinone ligand. ...
3 Φεβ 2021 · Now, using state-of-the-art technology, a team has examined how it interacts with other atoms, which they hope will shed new light on einsteinium and its neighbours on the periodic table.
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...
Einsteinium (Es), synthetic chemical element of the actinoid series of the periodic table, atomic number 99. Not occurring in nature, einsteinium (as the isotope einsteinium-253) was first produced by intense neutron irradiation of uranium-238 during the detonation of nuclear weapons.
