Question

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

Answer 1

Ionisation enthalpy is the minimum remove an electron from the outermost shell of a neutral isolated gaseous atom in it 's ground state.

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.
