[11] [12] Uranium metal has a very high density of 19.1 g/cm 3, [13] denser than lead (11.3 g/cm 3), [14] but slightly less dense than tungsten and gold (19.3 g/cm 3). [15] [16] Uranium metal reacts with almost all non-metallic elements (except noble gases) and their compounds, with reactivity increasing with temperature. [17]
Uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), uranium is 68.4% more dense than lead. Depleted uranium, which has about the same density as natural uranium, is used when this high density is desirable but the higher radioactivity of natural uranium is not.
New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum. New York: D. Van Nostrand ...
It became popular in the U.S. and uranium was widely used to color glassware until 1943, when the government started regulating its use so that they could save uranium to build atom bombs.
Density criteria range from above 3.5 g/cm 3 to above 7 g/cm 3. [17] Atomic weight definitions can range from greater than sodium (atomic weight 22.98); [ 17 ] greater than 40 (excluding s- and f-block metals, hence starting with scandium ); [ 18 ] or more than 200, i.e. from mercury onwards. [ 19 ]
In terms of density, m = ρV, where ρ is the volumetric mass density, V is the volume occupied by the mass. This energy can be released by the processes of nuclear fission (~ 0.1%), nuclear fusion (~ 1%), or the annihilation of some or all of the matter in the volume V by matter–antimatter collisions (100%).
