Classification Of Elements And Periodicity In Properties Ques 295
Question: The first ionisation enthalpies for two isotopes of the same elements are
Options:
A) same
B) different
C) some what different
D) $ |E_1=2|{E_{(II\text{ isotope)}}} $ (n isotope)
Show Answer
Answer:
Correct Answer: A
Solution:
[a] First ionization enthalpies of two isotopes of the same element are expected to be same because ionization enthalpy depends upon the electronic configuration and effective nuclear charge isotopes of a element have same electronic configuration and thus the same nuclear charge.
