The electrons of sodium, shell by shell
physical
Sodium's eleven electrons fill the shells in a fixed order — 1s² 2s² 2p⁶ 3s¹ — and that one lonely outer electron is the whole reason sodium is so reactive. Worked & sealed by the engine — Z=11 ground state = 1s² 2s² 2p⁶ 3s¹. [HOLDS; open the seal to re-check.]
