Miscellaneous Tables and Data

Abstract

The usual arrangement of elements in the periodic table makes use of the regularity of the atomic number and atomic weights to categorize the properties of the elements. An alternative categorization is to use the Mendeleev number and chemical scale proposed by Pettifor [1984] and shown in Table 11.1. The Mendeleev number is similar to the atomic number, but the basis for the ordering is the structure the element possesses. The chemical scale is analogous to the electronegativity scale, and the larger the number the more reactive is the element. This categorization is useful for creating structure maps of binary and ternary compounds to determine probable existence of a compound. See Pettifor [1984, 1985, 1986] and Pettifor and Podloucky [1985, 1986] for further details.
