Uranium - Wikipedia


Uranium metal has a very high density of 19.1 g/cm 3, denser than lead (11.3 g/cm 3), but slightly less dense than tungsten and gold (19.3 g/cm 3). Uranium metal reacts with almost all non-metal elements (with the exception of the noble gases) and their compounds, with reactivity increasing with temperature.
