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



Q.25:- Would you expect the first ionization enthalpies for two isotopes of the same element to be the same or different? Justify your answer.

 

 

Answer:- 



Ionization enthalpy, among other things, depends upon the electronic configuration (number of electrons) and nuclear charge (number of protons). Since isotopes of an element have the same electronic configuration and same nuclear charge, they have same ionization enthalpy.
