The lanthanide elements from lanthanum to lutetium inclusive are incorporated into the body of the periodic table. They are subdivided into three sub-groups according to their important oxidation states: La to Sm, Eu to Tm, Yb and Lu, so that Eu and Yb fall directly below Ba; La, Gd, Lu form a column directly below Y; Ce and Tb fall in a vertical line between Zr and Hf. Pm falls below Tc; both are radioactive, and not naturally occurring. The elements with easily attained 2+ and 4+ oxidation… Expand
On the ‘true position’ of hydrogen in the Periodic Table
Several attempts are known lately intending to point to ‘the proper place’ for hydrogen (sometimes also helium) in the Periodic Table of the elements. There are altogether five different types ofExpand

Accommodation of the Rare Earths in the Periodic Table
Synopsis Download full-size image This chapter gives an overview of the evolution of the position of the rare earths in the periodic table, from Mendeleev’s time to the present. Three fundamentallyExpand
Where to put hydrogen in a periodic table?
A modification of the regular medium-form periodic table is presented in which certain elements are placed in more than one position. H is included at the top of both the alkali metals and theExpand
The periodic table and the physics that drives it
Mendeleev’s introduction of the periodic table of elements is one of the most important milestones in the history of chemistry, as it brought order into the known chemical and physical behaviour ofExpand
A Study of the Physical and Mechanical Properties of Lutetium Compared with Those of Transition Metals: A Data Mining Approach
In this article, we study the physical and mechanical properties of lutetium, which will be compared with the elements of the third-row transition metals (Cs, Ba, Hf, Ta, W, Re, Os, Ir, Pt, Au, Tl,Expand
Low Temperature Water Gas Shift: Evaluation of Pt/HfO2 and Correlation between Reaction Mechanism and Periodic Trends in Tetravalent (Ti, Zr, Hf, Ce, Th) Metal Oxides
It is well-known that catalysts containing small quantities of noble metals (e.g., Pt, Au) that are highly dispersed on Group IV and related tetravalent metal oxides (e.g., TiO2, ZrO2, CeO2, ThO2)Expand
A century on from Dmitrii Mendeleev: tables and spirals, noble gases and Nobel prizes
Mendeleev’s failure to represent the periodic system as a continuum may have hidden from him the space for the noble gases. A spiral format might have revealed the significance of the wide gaps inExpand
MWCNTs based sorbents for nuclear waste management: A review
Abstract Multi walled carbon nanotubes (MWCNTs) based adsorbents have high sorption efficacy, fast sorption rate, selectivity, and reusability. All these features highlight that MWCNTs basedExpand
Newlands revisited: a display of the periodicity of the chemical elements for chemists
This is a periodic table explicitly for chemists rather than physicists. It is derived from Newlands’ columns. It solves many problems such as the positions of hydrogen, helium, beryllium, zinc andExpand


The positions of lanthanum (actinium) and lutetium (lawrencium) in the periodic table
The debate as to whether lanthanum and actinium or lutetium and lawrencium should be placed in group IIIB of the periodic table along with scandium and yttrium has along but poorly publicized history.
Special or anomalous chemical effects are examined in relation to periodic-table trends, and the degree to which these are relativistic effects are determined. It is noted that the degree to whichExpand
The First Subatomic Explanations of the Periodic System
Attempts to explain the periodic system as a manifestation of regularities in the structure of the atoms of the elements are as old as the system itself. The paper analyses some of the most importantExpand

Since the mid-18th century, a new element has been discovered on the average of every two-and-a-half years. Hypothetically extending the periodic table beyond its current seventh row is discussedExpand
Melting Point, Density, and Reactivity of Metals
The density and melting point of a metal, taken together, can give a useful qualitative guide to the chemical reactivity of the metal. A high density and high melting point indicate a low reactivity;Expand

The chemical properties of gold are strongly influenced by relativistic effects, which qualitatively explains the stability of (solid or liquid) cesium auride, Cs(+)Au(-), and other systems with Au(-) ions. Expand
