Upper Limit of the Periodic Table and the Future Superheavy Elements
CLASSROOM Rajarshi Ghosh Upper Limit of the Periodic Table and the Future Department of Chemistry The University of Burdwan ∗ Superheavy Elements Burdwan 713 104, India. Email: [email protected] Controversy surrounds the isolation and stability of the fu- ture transactinoid elements (after oganesson) in the periodic table. A single conclusion has not yet been drawn for the highest possible atomic number, though there are several the- oretical as well as experimental results regarding this. In this article, the scientific backgrounds of those upcoming super- heavy elements (SHE) and their proposed electronic charac- ters are briefly described. Introduction Totally 118 elements, starting from hydrogen (atomic number 1) to oganesson (atomic number 118) are accommodated in the mod- ern form of the periodic table comprising seven periods and eigh- teen groups. Total 92 natural elements (if technetium is consid- ered as natural) are there in the periodic table (up to uranium hav- ing atomic number 92). In the actinoid series, only four elements— Keywords actinium, thorium, protactinium and uranium—are natural. The Superheavy elements, actinoid rest of the eleven elements—from neptunium (atomic number 93) series, transactinoid elements, periodic table. to lawrencium (atomic number 103)—are synthetic. Elements after actinoids (i.e., from rutherfordium) are called transactinoid elements. These are also called superheavy elements (SHE) as they have very high atomic numbers. Prof. G T Seaborg had Elements after actinoids a very distinct contribution in the field of transuranium element (i.e., from synthesis. For this, Prof. Seaborg was awarded the Nobel Prize in rutherfordium) are called transactinoid elements. 1951.

INTRODUCTION We started to study the solid state chemistry of the actinide pnic• tides and chalcogenides in order to compare the properties of 4f and 5f electrons in semi-metallic compounds. In the actinide metals up to pluto• nium, the 5f orbitals take a prominent part in the bonding, leading to physical properties and particularly to crystal structures different from those of the rare-earth metals. On the other hand, ionic compounds, such as halides, have the same crystal structures in both actinide and lanthanide series when the elements have close ionic radii, and exhibit the 4f and 5f contractions respectively. In chalcogenides and pnictides the actinide elements do not make a uniform series since they can form compounds which are diffe• rent in composition and crystal structure as well. Two distinct groups are found : the uranium type compounds, and the rare-earth type compounds including those of plutonium, americium and curium. Neptunium is generally an intermediate element giving both types of compounds so that we shall review first the crystal chemistry of neptunium chalcogenides and pnictides. The repartition of the actinide s into two groups, depends upon the valency state of the actinide element : 4+ cations lead to uranium type chalcogenides and pnictides, while 3+ cations lead to rare-earth type compounds.
