This compact notation efficiently communicates the distribution of electrons across the subshells without drawing detailed orbital diagrams. The primary directive is the Aufbau principle, which translates to "building up" in German.
Test Your Understanding of Sodium's Electron Configuration
This accounts for ten electrons, completing the neon core. 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.
To arrive at the configuration for sodium, one must sequentially fill the 1s, 2s, 2p, 3s, and 3p subshells, adhering to the Pauli Exclusion Principle and Hund's Rule along the way. Sodium, represented by the symbol Na and atomic number 11, serves as a fundamental example in introductory chemistry when explaining the ground state electron configuration of an atom.
