Binding energy

Dear Marton and Roberto,

I hope you are both alright and in good health considering everything that is going on with the corona virus. I completely understand if you won't be able to answer my question because of health or working conditions.

My question is about the binding energy of molecules to a surface. Binding energy of water on water is in the range of 0.25-0.6 eV. (sojourn times of microseconds) Binding energies for water on metal range from 0.6 to 1.05 eV or so (sojourn times from milliseconds to days).
