Overview

Einsteinium is a member of the actinide family. The actinide elements are found in Row 7 of the periodic table, a chart that shows how chemical elements are related to each other. The actinides fall between radium (element number 88) and rutherfordium (element number 104). They are usually listed in a separate row at the very bottom of the periodic table.

Einsteinium is also a transuranium element. Transuranium elements are those beyond uranium on the periodic table. Uranium has an atomic number of 92, so elements with larger atomic numbers are transuranium elements.
