    Chemistry as a Creative Science.Le Grande O. Dolino - 2018 - Foundations of Chemistry 20 (1):3-13.
    How do we teach chemistry as a different science from physics? This paper looks into a fundamental distinguishing property of chemistry as a science. It is characterized in this paper that chemistry, unlike many other sciences that are largely descriptive, is primarily creative. In this sense, the various fields of chemistry may seek to create as an end goal, and not merely to create as a means to an end as commonly seen in allied sciences. This distinction is important as (...)

    Basic Principles of the Strategy Concerning the Elucidation of Configuration of Chiral Centers of Linear Isomeric Aldohexoses.Dumitru Petru Iga - 2018 - Foundations of Chemistry 20 (1):31-41.
    Fischer’s approach for structure elucidation of linear aldohexoses is still the most widespread alternative in textbooks for carbohydrates. However, in post-Fischer era, a series of remarkable discoveries and inventions were made in different laboratories, and by their use a more comprehensive and coherent strategy for structure elucidation of linear isomeric aldohexoses can be elaborated. Fischer used the exceptional properties of d-mannose for the knowledge of configuration of C-2 and called it the key of the gate to stereochemistry. We bring the (...)

    Valencies of the Lanthanides.David A. Johnson & Peter G. Nelson - 2018 - Foundations of Chemistry 20 (1):15-27.
    The valencies of the lanthanides vary more than was once thought. In addition to valencies associated with a half-full shell, there are valencies associated with a quarter- and three-quarter-full shell. This can be explained on the basis of Slater’s theory of many-electron atoms. The same theory explains the variation in complexing constants in the trivalent state. Valency in metallic and organometallic compounds is also discussed.

    A Representation of the Periodic System Based on Atomic-Number Triads.Alfio Zambon - 2018 - Foundations of Chemistry 20 (1):51-74.
    In the last decade, the notion of triad was reintroduced by Eric Scerri, who suggested it as a possible categorical criterion to represent chemical periodicity. In particular, he reformulated the notion of triad in terms of atomic number instead of atomic weights; in this way, the value of the intermediate term of the triad became the exact average of the values of the two extremes. Following the inspiration of Scerri’s work, the main purpose of this article is to obtain a (...)
