AN INVERSE LINEAR RELATION BETWEEN: ATOMICNUMBERPLUSVALENCE; AND HYDRATION NUMBERS DERIVED FROM IONIC WEIGHTS CALCULATED AS INVERSESQUAREOFCONDUCTANCE/MOBILITY PER LAW OF KINETIC ENERGY by Stuart Hale Shakman, P.O. Box 382, Santa Monica, CA90406; ae735@lafn.org 26 September 1996 For cations with Z = 319^{1}  Li+, Na+, Mg++, Al+++ and K+  an approximate inverse linear relation between calculated hydration numbers (H) and sums of atomic number (Z) plus valence (C) is exhibited when solute ionic weight is calculated as the inversesquareofconductance and adjusted to a base weight value of 85.4768 for Rb+. The subtraction of atomic weights (A.W.) from solute ionic weights yields calculated values for the weights of water of hydration, against zero^{2} for Rb+; weights of water of hydration, divided by the weight of a single water unit, 18, yield calculated hydration numbers. (See Table 1). Figure 1 plots calculated hydration numbers against respective sums of atomic number and valence. The inverse linear result shown in Figure 1 illustrates the essential foundation of a methodology first discussed by L. H. Flint in 1932^{3}, wherein, for the hydrated lighter ions, Z + C + H was proposed to equal 23. As shown in Table 1 and Figure 1, calculations for H+, OH, and the base ion, Rb+, also yield an approximate linear result at H = 0. The suggestion that relatively large conductivities of H+ and OH indicate they are not hydrated was first made by Abegg and Bodlander^{4}, first calculated by Flint^{3}, and explained by Flint as evidencing dehydration due to the electrical stress imposed in measuring conductance^{5}. 1.
