Liquid ammonia, which is a good solvent for many salts, dissolves alkali and alkaline earth metals forming metastable solutions which have many unusual properties. These electrical conductances of the blue dilute solutions of the metals are comparable to the conductances of ordinary electrolytic solutions, whereas the concentrated solutions show metallic conduction comparable in magnitude to the conductances of some metals. In contrast to the electrolytic solutions which always show increasing densities substantially lower than that of the solvent. The viscosity of the sodium solutions is less than the viscosity of the solvent, which is contrary to what has been observed for the electrolytic solutions. The paramagnetic susceptibility of the dilute metal solutions decreases rapidly with increasing concentration and decreasing temperature. [TRUNCATED]
