What Is A Chemical Element?
The current (IUPAC) definition of “chemical element” has two parts. The first part describes a concept on which chemists generally agreed when important aspects of the structure of chemical substances became clear by the middle of the twentieth c

Intra-molecular connectivity (that is, chemical structure) does not emerge from computations based on fundamental quantum-mechanical principles. In order to compute molecular electronic energies (of C3H4 hydrocarbons, for instance) quantum chemists m

In 1931 eminent chemist Fritz Paneth maintained that the modern notion of “element” is closely related to (and as “metaphysical” as) the concept of element used by the ancients (e.g., Aristotle). On that basis, the element chlorine (properly

The main scientific problems of chemical bonding were solved half a century ago, but adequate philosophical understanding of chemical combination is yet to be achieved. Chemists routinely use important terms (“element,” “atom,” “molecule,

During a long and distinguished career, Belgian physical chemist Ilya Prigogine (1917–2003) pursued a coherent research program in thermodynamics, statistical mechanics, and related scientific areas. The main goal of this effort was establishing th

Covalent bonding within chemical molecules and the internal electronic structure of atoms involve closure of phase relations in electronic wave functions, as suggested de Broglie by many years ago. The structures of crystals involving positive and ne

What, precisely, is `salt'? It is a certainwhite, solid, crystalline, material, alsocalled sodium chloride. Does any of that solidwhite stuff exist in the sea? – Clearly not.One can make salt from sea water easily enough,but that fact does not esta
