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 ...

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 ]
It is the acid anion that influences the degree of complexing—how atoms connect to a central atom—of the plutonium species. 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. [5] A +8 oxidation state is possible as well in the volatile tetroxide ...
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.
