Furthermore, he proved that this had no connection with the phenomenon of phosphorescence, as both uranic and uranous salts were active and the latter show no phosphorescence.

From Project Gutenberg

Under the luminous agency the uranic nitrate is first reduced, then the uranous oxide acts on the cupric nitrate, forming cupric oxide, which is finally reduced to the metallic state.

From Project Gutenberg

Uranium forms two families of salts, uranous and uranic; corresponding to the oxides UO2 and UO3 respectively.

From Project Gutenberg

Uranous salts are converted into uranic by boiling with nitric acid or other oxidising agents.

From Project Gutenberg

M. Becquerel established, after some hesitations natural in the face of phenomena which seemed so contrary to accepted ideas, that the radiating property was absolutely independent of phosphorescence, that all the salts of uranium, even the uranous salts which are not phosphorescent, give similar radiant effects, and that these phenomena correspond to a continuous emission of energy, but do not seem to be the result of a storage of energy under the influence of some external radiation.
