Solvated electrons behave as independent chemical species in metal-ammonia solutions
Solvated electrons in metal-ammonia solutions act as localized, independent chemical species within solvation shells at low concentrations before transitioning to a delocalized, metal-like state at higher concentrations.
The retrieved literature (such as papers 0 and 9) directly discusses the nature of solvated electrons in metal-ammonia solutions, confirming that at low to moderate concentrations they exist as localized species within solvation shells (behaving as independent chemical entities with distinct paramagnetic and diamagnetic states) before undergoing a transition to a delocalized, metallic state at higher concentrations. The claim is well-supported by foundational and recent theoretical treatments.
