Question

would you expect ionozation enthalpies of two isotopes of same element same or different​

Answer 1

isotopes have similar chemicals properties due to same no of electron hence we will expected them to have similar IE

Answer 2

Answer:

Ionization enthalpy of any atom relies on its number of protons and electrons. But, the isotopes of any element have equal number of electrons and protons. Thus, the 1st ionization enthalpy of two isotopes of a single element is same.
