A periodic-like table of space groups [PDF]

open access: goldActa Crystallographica Section E: Crystallographic Communications, 2023
There are about 100 chemical elements, and 200 space groups, rounding to the nearest hundreds. The elements, by virtue of the iconic periodic table, which hangs in schoolrooms worldwide, are part of our common culture.

The Periodic Table and the Platinum Group Metals

open access: diamondPlatinum Metals Review, 2008
The year 2007 marked the centenary of the death of Dmitri Mendeleev (1834–1907). This article discusses how he and some of his predecessors accommodated the platinum group metals (pgms) in the Periodic Table, and it considers the placing of their three transuranic congeners: hassium ( 108 Hs ...

Model Equation Based on the 8 Groups and the 7 Periods in the Periodic Table of Elements

open access: hybridInternational Research in Education, 2021
The periodic table of chemistry contains all synthetic and naturally occurring elements. The elements are arranged in seven horizontal periods from left to right with increasing atomic number. The periodic table is divided into two groups: metals and nonmetals, within elements moving from left to right, the elements get less metallic, culminating in ...

The location and composition of Group 3 of the periodic table [PDF]

open access: hybridFoundations of Chemistry, 2020
AbstractGroup 3 as Sc–Y–La, rather than Sc–Y–Lu, dominates the literature. The history of this situation, including involvement by the IUPAC, is summarised. I step back from the minutiae of physical, chemical, and electronic properties and explore considerations of regularity and symmetry, natural kinds, and quantum mechanics, finding these to be ...

Alkali Metal Cation Affinities of Anionic Main Group‐Element Hydrides Across the Periodic Table

open access: greenChemistry – An Asian Journal, 2017
AbstractWe have carried out an extensive exploration of gas‐phase alkali metal cation affinities (AMCA) of archetypal anionic bases across the periodic system using relativistic density functional theory at ZORA‐BP86/QZ4P//ZORA‐BP86/TZ2P. AMCA values of all bases were computed for the lithium, sodium, potassium, rubidium and cesium cations and compared

Group Theoretical Description of Periodic System of Elements: II. Seaborg Table

open access: bronzeMathematical structures and modeling, 2019
Group theoretical description of Seaborg table (an eight-periodic extension of the Mendeleev table) is considered in the framework of the Rumer-Fet model. The mass formula, which allows one to provide a termwise mass splitting of the basic representation of the Rumer-Fet group, is introduced.
