Plutonium is an element where the 5f electrons are the transition border between delocalized and localized; it is therefore considered one of the most complex elements.[16] It is a radioactive actinide metal whose isotope, plutonium-239, is one of the three primary fissile isotopes[17] (uranium...
This fluctuating number of outer-shell electrons explains why plutonium isn't magnetic: In order for an atom to interact with magnets the unpaired electrons in its outer shell must line up in amagnetic field. [Read more about plutonium's missing magnetism] Plutonium's most stable isotope, pluto...
Cerium is used as a chemical simulant of plutonium for development of containment, extraction, and other technologies.[41] Electronic structure Plutonium is an element in which the 5f electrons are the transition border between delocalized and localized; it is therefore considered one of the most co...
Plutonium is not magnetic. Other members of the element group stick to magnets, but plutonium can have a variable number of electrons in its valence shell, which makes it difficult for the unpaired electrons to align in a magnetic field. ...
The researchers found that the number of valence electrons in plutonium's 5f orbital fluctuates. The research may be useful in understanding the byproducts of nuclear reactors.SteinBenjamin P.Physics Today
that there are pairing correlations in all f-electron metals, and that the anomalous properties of the elemental actinides in the vicinity of Np/Pu/Am,even at elevated temperatures, is associated with a critical point in the variation of the density of paired electrons with atomic number.doi...
同义词:Puatomic number 94 学习怎么用 双语例句 用作名词(n.) In October, North Korea exploded its first nuclear device, made using plutonium. 10月,北朝鲜爆炸了他的第一个由钚制造的核装置。 Uranium and plutonium are radioelements, which are widely used in the military area. ...
The surface of plutonium burns in the presence of oxygen in the air, like an ember of a fire. Radium and the hydrogen isotope tritium emit particles that excite the electrons of fluorescent or phosphorescent materials. The stereotypical greenish glow comes from a phosphor, usually doped zinc sulf...
