How does the Pauli Exclusion principle explain ionization E?

    How does the Pauli-exclusion principle explain ionization energy trends? Is it just that as you move down the periodic table, the electrons experience repulsion between each other, and thus the atoms get bigger?

    Pauli principle alone cannot explain the ionization energy trend, there are also nuclear charge and subshell wavefunction which contribute more to this trend.

    Does the first chart & explanation here answer your question?


    Or try further down that same page...."Quantum Mechanical Explanation".
