Further, ambiguities in electron configurations and the breakdown of assigning a dominant configuration, owing to configuration mixing and dense spectra for the heaviest elements in the periodic table. For the short-lived transactinides, the nuclear stability becomes an important factor in chemical ...
Depending upon the type of orbital receiving the valance electron the elements are classified into four blocks such as s-block, p-block, d-block, f-block. In s-block elements, valance electrons enter an s-orbital. Group-IA and group-IIA belong to this block in the periodic table. d-blo...
John Newlands compared elements to musical notes with his law of octaves. As on a scale, every eighth element would share similar properties when arranged by increasing atomic weight. Newlands did not account for exceptions, however, and it was only upon establishment of the Periodic Table that...
Inthe accompanying table, which isa relatively simple type of periodic table, each position gives the name and chemical symbol for the element assigned to that position; its atomic number; itsatomic weight(the weighted average of the masses of its stable isotopes, based on a scale in which carb...
These metals have very unique properties, owing to their f-orbital arrangements and unstable nuclei. As an example,uranium(U) is a part of this group. What are transition and post-transition metals? Thetransition metalsinclude 34 metals in the middle of the periodic table. These metals are na...

Baryon resonances corresponding to the orbital configuration with two valence quarks in excited states couple strongly to the \\pi \\pi N \\pi \\pi N -channel, but not to the \\pi N \\pi N channel. At low energy scale up to 2000 MeV, the obtained numerical estimations for the SU(...

Periodic table - Elements, Groups, Properties: The noble gases—helium, neon, argon, krypton, xenon, radon, and oganesson—have the striking chemical property of forming few chemical compounds. This property would depend upon their possessing especially
