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.
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...
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 · 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.
9 Ιουν 2023 · In the case of einsteinium and its neighbors at the bottom of the periodic table, it's the sheer size of their atoms, explains Joseph Glajch, a pharmaceutical chemist who has worked extensively with other radioactive elements used for medical imaging.
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 · The material was made at Oak Ridge National Laboratory’s High Flux Isotope Reactor, one of only a few places in the world that is capable of making einsteinium, which involves bombarding curium targets with neutrons to trigger a long chain of nuclear reactions.
