Would you expect the first ionization enthalpies for 2 isotopes of the same element to be the same or different ??? justify your answer .

Expert Answer:

Ionisation enthalpy is the minimum amount of energy required to remove an electron from the outermost shell of a neutral isolated gaseous atom in it 's ground state. Since the isotopes of same element have the same atomic number, they have the same number of electrons (and protons) and differ only in the number of neutrons. Hence the ionisation energy for two isotopes of an element should be same.
