This bond is non-directional, resulting in a rigid crystal lattice where every sodium ion is surrounded by chloride ions and vice versa. By losing that single valence electron, the sodium atom achieves the same electron configuration as neon, the preceding noble gas.
Sodium Ion Size Compared Neutral Atom
Within the intricate framework of matter, the behavior of the electron defines the chemical identity of every element. Property Neutral Sodium Atom (Na) Sodium Ion (Na⁺) Electron Configuration 2, 8, 1 2, 8 Charge Neutral Positive (+1) Reactivity Highly Reactive Stable in ionic Compounds Size Larger Smaller (due to loss of electron and reduced electron-electron repulsion) The Ionic Environment: Sodium in Solution and Solids.
The electron configuration is 2-8-1, indicating two electrons in the first shell, eight in the second, and a single electron in the third and outermost shell. Why Sodium Loses an Electron The driving force behind sodium's reactivity is its desperate pursuit of stability, specifically the stable electron configuration of a noble gas.
Sodium Ion Size Compared Neutral Atom
The energy required to remove this electron is relatively low, explaining why sodium readily donates it to other elements. The sodium ion is a hard cation with a relatively low charge density, meaning its positive charge is spread over a larger volume compared to smaller, highly charged ions like aluminum.
