Einsteinium (pronounced /aɪnˈstaɪniəm/, eyen-STYE-nee-əm) is a metallic synthetic element. On the periodic table, it is represented by the symbol Es and atomic number 99. It is the seventh transuranic element, and an actinoid. It was named in honor of Albert Einstein.
Its position on the periodic table indicates that its chemical and physical properties are similar to other metals. Though only small amounts have been made, it has been determined to be silver-colored. According to tracer studies conducted at Los Alamos National Laboratory using the isotope Es, this element has chemical properties typical of a heavy trivalent, actinide element.
Like all synthetic elements, isotopes of einsteinium are extremely radioactive, and are considered highly toxic.
Einsteinium does not occur naturally in any measurable quantities. The modern process of creating the element starts with the irradiation of plutonium-239 in a nuclear reactor for several years. The resulting plutonium-242 isotope (in...
