WebThe radius of the hydrated proton appears in the Born equation for calculating the hydration enthalpy of hydronium. Interaction of free protons with ordinary matter [ edit ] Although protons have affinity for oppositely charged electrons, this is a relatively low-energy interaction and so free protons must lose sufficient velocity (and kinetic energy ) in order … WebA simple calculation was performed to estimate the number of H 2 O molecules in the radial direction (the hydration number) as ( rs − Rion )/ RH2O for each alkali metal ion ( Table 2 ). The hydration number of Li + is about 2 in the radial direction, and larger alkali metal ions are less hydrated.
