The arrangement of 1s² 2s² 2p⁶ 3s¹ defines the element, dictates its position on the periodic table, and is the direct cause of its vigorous chemical properties. Step-by-Step Electron Filling For the 11 electrons of a neutral sodium atom, the filling process occurs as follows: the first two electrons enter the 1s orbital, the next two fill the 2s orbital, and the subsequent six occupy the 2p orbitals.

Understanding this distribution of electrons is essential for predicting chemical behavior, bonding patterns, and the physical properties of the metal. This electron is loosely bound to the nucleus because it is shielded by the ten inner electrons of the neon core, experiencing a weaker effective nuclear charge.
This compact notation efficiently communicates the distribution of electrons across the subshells without drawing detailed orbital diagrams. Summary and Significance To summarize, the ground state electron configuration of sodium is a foundational concept that illustrates the core principles of atomic structure.
