The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. Electron configurations describe where electrons are located around the nucleus of an atom. For example, the electron configuration of lithium, 1s²2s¹, tells us that lithium has two electrons in the 1s subshell and one electron in the 2s subshell.
