[28] [43] Computational chemistry methods indicate an enhanced covalent character in the plutonium-ligand bonding. [15] [43] Powders of plutonium, its hydrides and certain oxides like Pu 2 O 3 are pyrophoric, meaning they can ignite spontaneously at ambient temperature and are therefore handled in an inert, dry atmosphere of nitrogen or argon ...
Various oxidation states of plutonium in solution. Plutonium compounds are compounds containing the element plutonium (Pu). At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized. [1] The element displays four common ionic oxidation states in aqueous solution and one rare one: [2] Pu(III), as Pu 3+ (blue lavender)
These are in the form of RE a M b Pn c, where M is a carbon group or boron group element and Pn is any pnictogen except nitrogen. These compounds are between ionic and covalent compounds and thus have unusual bonding properties. [4] These elements are also noted for their stability in compounds due to their tendency to form covalent double ...
Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.

Palladium is a chemical element; it has symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1802 by the English chemist William Hyde Wollaston . He named it after the asteroid Pallas (formally 2 Pallas), which was itself named after the epithet of the Greek goddess Athena , acquired by her when she slew ...
Neptunium melts at 639 ± 3 °C: this low melting point, a property the metal shares with the neighboring element plutonium (which has melting point 639.4 °C), is due to the hybridization of the 5f and 6d orbitals and the formation of directional bonds in the metal. [10]
The name was also chosen to continue the tradition of the four stable halogens, where the name referred to a property of the element. [97] Corson and his colleagues classified astatine as a metal on the basis of its analytical chemistry. [98] Subsequent investigators reported iodine-like, [99] [100] cationic, [101] [102] or amphoteric behavior.
