iscaesium-137.Iodine-129is one of the major radioactive elements released from reprocessing plants. In nuclear reactors both caesium-137 andstrontium-90are found in locations remote from the fuel. This is because these isotopes are formed by thebeta decayofnoble gases(xenon-137, with a 3.8-min...

Xenon, chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colorless, odorless, and tasteless.
These correspond to the noble gases, helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The electronic structure of some of these stable atoms is shown in Figure 1.4.3. All of the other elements can react with other atoms, in order to become more ...
This technique was applied for the shake-up satellites in photoelectron spectra of noble gases [28,29,30] and extended to valence and core Auger transitions [31,32,33,34,35]. Some predictions of these theoretical results for the valence Auger transitions were confirmed experimentally [36,37]....
Neutral atomic radii of dissolved noble gas elements in condensed phases are obtained by treating the neutral atoms as “ions” of zero oxidation state and by interpolation from a plot of radius vs. oxidation state for isoelectronic ions. The major assum
noble gases, and halogens have been detected by coupling a gas chromatographic unit to a low-pressure plasma. DL-AAS can be utilized for elemental speciation as has been demonstrated by the detection of Cr(III) and Cr(VI) species in water using a commercial high-performance liquid chromatograp...
They travel outside the nucleus of an atom in distinct routes called orbitals. Neutrons have no charge and have an atomic mass of about one atomic mass unit. They are present in the nucleus. A nucleon can be either a proton or neutron and is a part of the atom's nucleus....
