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.
17 Σεπ 2020 · Here is a chart of element charges and an explanation of how to find the charge of an element if you don’t know it. The difference between charge, oxidation state, and valence is explained, too. You can download and print these graphics and tables for references.
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 · This article was amended on February 17, 2021 to clarify the definition of valence and to make clear that einsteinium’s valence helps us understand, not organise, its position in the periodic...
28 Αυγ 2016 · Simple explanation: The size of the cations increases down the group, and group elements form singly ionised cations (have a charge of +1), so the charge density decreases down the group. Extent of solvation is proportional to charge density, and consequently lithium ions would be the most solvated, hence least mobile.
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 · And so, when elements previously unknown to science were discovered in the chemical debris of a nuclear explosion 69 years ago, it was fitting that scientists named what they found after the great physicist — adding “ einsteinium ” to the periodic table.
