Abstract
The adsorption of the ions has been studied using the molecular dynamics technique. Increasing the mass of the nonbridging oxygen altered the alkali adsorption. The dynamic behaviour of the alkalis was coupled with the ability of the nonbridging oxygen to accommodate the adsorbates. Increasing the mass of the nonbridging oxygen increased both the mobility of the ions and the elapsed time before they bonded to the substrate. Differences between the behaviour of potassium and lithium adsorbates were attributed to the difference between the mass ratio of the alkali and that of the nonbridging oxygen.
