The thing is, an electron in the middle of a cavity formed by the solvent molecules is not free; hence the word "ammoniated". Add a comment. Active Oldest Votes.

NNAs are objective features of the density distribution: local maxima not located near any nuclei. They appear in ab initio wavefunctions and DFT both. So never mind, I guess.

Humphry Davy was fascinated by the bronze and blue colours, which he observed in , shortly after he had discovered sodium and potassium. Photoelectron spectra suggest that individual solvated electrons gradually coalesce as their concentration is increased, first forming spin-paired dielectons and then a metallic liquid.

She notes that there is a big gap in the measurements between the most concentrated and the second most concentrated solutions. For this, the team will need to add alkali metal to water, which usually results in an explosive reaction. If the researchers succeed, it would allow them to make a material that has been proposed to exist only at extremely high pressures. Voice of The Royal Society of Chemistry. One chemistry professor received four month prison sentence for producing the drug in a university lab, while another was acquitted.

A computational model reveals how solvated electrons green blobs are surrounded by a diffuse shell of ammonia molecules.

As lithium metal dissolves in liquid ammonia, solvated electrons give the solution a dark blue color at low concentrations top , and a metallic bronze sheen at higher concentrations bottom.
