Additionally, the formal +2 oxidation state of plutonium is known in the complex [K(2.2.2-cryptand)] [Pu II Cp″ 3], Cp″ = C 5 H 3 (SiMe 3) 2. [37] A +8 oxidation state is possible as well in the volatile tetroxide PuO 4. [38] Though it readily decomposes via a reduction mechanism similar to FeO 4, PuO 4 can be stabilized in alkaline ...
Plutonium-238 was the first isotope of plutonium to be discovered. It was synthesized by Glenn Seaborg and associates in December 1940 by bombarding uranium-238 with deuterons, creating neptunium-238. 238 92 U + 2 1 H → 238 93 Np + 2 n. The neptunium isotope then undergoes β − decay to plutonium-238, with a half-life of 2.12 days: [6] 238 ...
This makes plutonium very sensitive to changes in temperature, pressure, or chemistry, and allows for dramatic volume changes following phase transitions. [5] Unlike most materials, plutonium increases in density when it melts, by 2.5%, but the liquid metal exhibits a linear decrease in density with temperature. [ 6 ]

Decay heat as fraction of full power for a reactor SCRAMed from full power at time 0, using two different correlations. In a typical nuclear fission reaction, 187 MeV of energy are released instantaneously in the form of kinetic energy from the fission products, kinetic energy from the fission neutrons, instantaneous gamma rays, or gamma rays from the capture of neutrons.

When heated to 150–180 °C, it decomposes with autooxidation to plutonium (VI) with the formation of plutonyl nitrate (PuO 2 (NO 3) 2).Upon evaporation of concentrated nitric acid solutions of plutonium nitrate and alkali metal nitrates, double nitrates of the composition M 2 [Pu(NO 3) 6] are formed, where M = Cs +, Rb +, K +, Tl +, NH 4 +, analogous to ceric ammonium nitrate.
