Unveiling Sodium: Atomic Structure, Electron Configuration, And Chemical Reactivity
Sodium’s atomic number (11) reveals the presence of 11 protons, which in turn determines the number of electrons in a neutral sodium atom. Sodium’s electron configuration, 1s² 2s² 2p⁶ 3s¹, indicates that it has 11 electrons distributed among its energy levels. One valence electron in the outermost 3s orbital makes sodium highly reactive and eager…
