Periodic tableOxidation stateLanthanidesActinidesIn this note, we briefly compare oxidation states associated with adjacent rows in the periodic table. Or more precisely, we make comparisons for a few compounds containing elements from the first two rows in which a given value of the quantum number...
Metastable homonuclear diatomic trications X23+ for elements X from the first three rows of the periodic table Motivated by a systematic stability scan of the homonuclear diatomic systems with elements from hydrogen to argon, we investigated in detail the ensuing fi... Hogreve,H. - 《Computation...
We have revalued a large variety of bond energy terms involving atoms of the first rows of the Periodic Table. We describe a series of interesting applications based on these bond energy terms, namely the determination of enthalpies of atomization and stabilization energies and the rationalization ...
These detections unescapably lead to one (or a combination) of the two following consequences. Either the effective collision strengths 惟 for the transitions of the heavy ions 4p魏 and 5p魏 are, on average, at least 10 times larger than for the corresponding transitions of the light ions ...
This type is called a rectangular fiber core [6,7,8,9,10]. The rectangular fiber core is generally composed of multiple elliptical or circular holes to extend the mode field in the x direction, while a few elliptical or circular holes are adopted to limit the mode field in the y ...
