A solvated electron is a free electron in a solution, in which it behaves like an anion. [1] An electron's being solvated in a solution means it is bound by the solution. [ 2 ] The notation for a solvated electron in formulas of chemical reactions is "e − ".
During the solvation process, the “wet” electron oscillates rapidly between a large, quasi-free state and a localized state. During this phase, which lasts around 220 fs in pure water, the electron “digs” a solvation shell that afterwards hosts the electron, at which point it is referred to as a “hydrated” or “solvated electron ...
Free electron in physics may refer to: Electron, as a free particle; Solvated electron; Charge carrier, as carriers of electric charge; Valence electron, as an outer shell electron that is associated with an atom; Valence and conduction bands, as a conduction band electron relative to the electronic band structure of a solid
A sodium ion solvated by water molecules. Solvations describes the interaction of a solvent with dissolved molecules. Both ionized and uncharged molecules interact strongly with a solvent, and the strength and nature of this interaction influence many properties of the solute, including solubility, reactivity, and color, as well as influencing the properties of the solvent such as its ...
An electride is an ionic compound in which an electron serves the role of the anion. [1] Solutions of alkali metals in ammonia are electride salts. [2] In the case of sodium, these blue solutions consist of [Na(NH 3) 6] + and solvated electrons: Na + 6 NH 3 → [Na(NH 3) 6] + + e −. The cation [Na(NH 3) 6] + is an octahedral coordination ...
Finally, the solvated electron can react with solutes such as solvated protons or oxygen molecules to form hydrogen atoms and dioxygen radical anions, respectively. The fact that oxygen changes the radiation chemistry might be one reason why oxygenated tissues are more sensitive to irradiation than the deoxygenated tissue at the center of a tumor.
Metal aqua ions are always accompanied in solution by solvated anions, but much less is known about anion solvation than about cation solvation. [ 6 ] Understanding of the nature of aqua ions is helped by having information on the nature of solvated cations in mixed solvents [ 7 ] and non-aqueous solvents , such as liquid ammonia , methanol ...
