This document provides the electron configuration for all elements in the periodic table. It lists each element's atomic number, symbol, name, and the electrons in their K, L, M, and N electron shells. The elements are categorized as metals, metalloids, nonmetals, or unknown based on their chemical properties. Transition elements and inner transition elements are also noted.
