The Periodic Table and the Platinum Group Metals
Platinum 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),

The Periodic Table and Kinetics?
CHIMIA, 2019 Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later.

Molecules, 2022 The current discussion on whether scandium, yttrium and lanthanum should represent Group 3 in the Periodic Table or whether lutetium should replace lanthanum in the group has prompted us to further explore the structural chemistry of the Group 3 elements

Turkish Computational and Theoretical ChemistryThe article considers the periodic table of chemical elements, and that it is a graphic representation of the periodic law (PL), although more than 150 years have passed since the opening of the periodic law, there is no clear formulation of the mathematical formula of this law.

On the Importance of σ–Hole Interactions in Crystal Structures
Crystals, 2021 Elements from groups 14–18 and periods 3–6 commonly behave as Lewis acids, which are involved in directional noncovalent interactions (NCI) with electron-rich species (lone pair donors), π systems (aromatic rings, triple and double bonds) as well as ...

On the membership of group 3 of the periodic table: A new approach
THEORIA. An International Journal for Theory, History and Foundations of Science, 2019 In April 2015, an international team of researchers announced the measurement, for the first time, of the first ionization energy of lawrencium, a superheavy element of atomic number 103. The experimental result, published in the prestigious scientific journal Nature, led to the reopening of a long-standing debate that concerns the elements that should

C, 2020 The σ- and π-hole interactions are used to define attractive forces involving elements of groups 12–18 of the periodic table acting as Lewis acids and any electron rich site (Lewis base, anion, and π-system).
