The Periodic Table and Kinetics?

Abstract

Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later. To illustrate the systematic variation of kinetics across the periodic table we compare water residence times for monoatomic ions in aqueous solution. A tremendous variation of ?H2O by over 20 orders of magnitude is found, ranging from ~10 ps to about 200 years. Apart from some small +2 and +3 cations, all main group elements have very short residence times
