To visualize the electron arrangement in sodium (Na), start by considering the total number of electrons, which is 11. Sodium’s electron shell structure is crucial for understanding its chemical properties and behavior. Begin by filling the lowest energy orbitals first, following the Aufbau principle, the Pauli exclusion principle, and Hund’s rule. The first energy level accommodates 2 electrons, the second can hold up to 8, and the third holds the remaining 1 electron in the 3s orbital.
