Periodic Table of Ions

From Concept of Chemical Periodicity: from Mendeleev Table to Molecular Hyper-Periodicity Patterns E. V. Babaev and Ray Hefferlin, here.

"One intriguing problem that arises from with the periodic table of atoms is the possibility of constructing periodic systems of ions, V. K. Grigorovich, Periodic Law of Mendeleev and Electronic Structure of Metals, Nauka Publ.: Moscow, 1966 (in Russian). An atom can be completely or partially ionized to a cation by removing electrons or transformed into an anion by the addition of new electrons. The energy required for a few consecutive ionisations of atoms is plotted against the atomic number. One can see that the curves are periodic, and hence it is possible to construct periodic tables for mono-, di-, and multi- charged cations. If we look at the dispositions of the maxima and minima of the curves and compare them with those for atoms, it becomes evident that the magic numbers of electrons for ions are the same as for neutral atoms. Therefore, the number of electrons (but not the charge of the nucleus) is responsible for the periodicity of ions."

Discovery of Nobelium

No

Nobelium, atomic number 102, has a mass of 259 au.

Synthetic radioactive element.

Nobelium was first observed in 1966 by E. D. Donets, V. A. Shchegolev and V. A. Ermakov.

Rare Earth Pop Out Periodic Table

From Rare Earths, The Fraternal Elements by Karl A. Gschneidner Jr., United States Atomic Energy Commission Division of Technical Information Library of Congress Catalog Card Number: 65-60546 1964; 1966 (Rev.)

There is an interesting point made in the text concerning the term "Rare Earths":

"The name rare earths is actually a misnomer for these elements are neither rare nor earths. They are metals, and they are quite abundant. Cerium, which is the most abundant, ranks 28th in the abundances of the naturally occurring elements and is more plentiful than beryllium, cobalt, germanium, lead, tin, or uranium. The least abundant naturally occurring rare earth, thulium, is more plentiful than cadmium, gold, iodine, mercury, platinum, or silver. Indeed, 25% of the elements are scarcer than thulium."

Thanks to René for the tip!

Tottle's Periodic Table

Tottle CR 1974, The Science of Engineering Materials, reprint of 1966 ed., Heinemann Educational Books, London, p. 20

René Vernon writes:

I was drawn to the attached periodic table by the strange-looking arrangement of dividing lines, one "full" and one dashed, in the p-block.

Semimetals

Ge, As, Se, Sn, Sb, Te, Bi and Po are shown as semi-metals. Tottle does not explain the basis for this division.

Showing Sn as a semi-metal or metalloid is dubious. Sure, white-Sn becomes gray-Sn at a temperature of below 13.2 °C but even here it has the electronic band structure of a semi-metal.

The same can be said for Po which has electronic band structure of a true metal, unlike the situation in As, Sb and Bi, all of which have electronic band structures of semi-metals.

Metals & Nonmetals

Starting with H, note the left to right path of the full dividing line between metals and nonmetals is continuous, except for the unique break above Be, presumably to show that there is no element above Be. This is actually not well thought-out since the metallic or nonmetallic status of the IIA elements is not then clarified.

Tottle is further interesting since, as well as referring to metals and nonmetals in the periodic table sense he later includes a chapter on Metals and alloys, and a chapter on Non-metallic materials. Some examples given by him of non-metallic materials are alumina, magnesia, graphite, beryllia, titanium carbide, glass, rubber, nylon and wood. So, he here is mixing nonmetallic elements and nonmetallic materials (which is fine).

Tottle gets into trouble in his chapter on Metals and alloys, since he includes some discussion on interstitial solid solutions, such as cementite Fe3C, which is an insulator, and intermetallic compounds, which appears fine on the surface, until one realises that some intermetallic compounds are semiconductors, such as FeGa3, RuGa3, and IrGa3. I have never heard of semiconducting or insulating metals or alloys.
