The value of vague ideas in the development of the periodic system of chemical elements

The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific

In praise of triads

The article begins with a response to a recent contribution by Jensen, in which he has criticized several aspects of the use of triads of elements, including Döbereiner’s original introduction of the

Various forms of the periodic table including the left-step table, the regularization of atomic number triads and first-member anomalies

The relative virtues of 8- and 18-column periodic tables are discussed, followed by a brief mention of a 32-column table. Next, the left-step periodic table, as first introduced by Janet, is

Both Dobereiner’s original atomic weight triads and the recent atomic number triads are critically evaluated and found to be neither necessary nor sufficient to determine the degree of relatedness

Josiah Parsons Cooke, the Natural Philosophy of Sir John F. W. Herschel and the Rational Chemistry of the Elements

The natural philosophy of chemistry grew slowly until the articulation of the axiom of chemical atoms by John Dalton in the early nineteenth century. Sir John F. W. Herschel was one of the leading

Periodicity in Britain: The Periodic Tables of Odling and Newlands

Two British chemists, William Odling and John A. R. Newlands, published separate periodic arrangements of the elements in the middle 1860s, several years before Mendeleev’s first periodic table. This

Mendeleyev revisited

Despite the periodic table having been discovered by chemists half a century before the discovery of electronic structure, modern designs are invariably based on physicists’ definition of periods.
