Wet electrons
From Wikipedia, the free encyclopedia
Hydrogen atoms on water or hydroxide (OH) can be involved in hydrogen bonds or be dangling. Wet electrons are primarily stabilized by the dangling atoms on OH, which is more acidic than water, but the dangling atoms on water also contribute to the stabilization.
The process is like the lowest elevation path between valleys with a mountain between them. This option would take minimum effort. To transport an electron from solid to liquid, the minimum amount of energy you would have to provide corresponds to going through the wet electron state. Wet electrons are a transition state (saddle point) between electrons in liquid and electrons in solid.
