Aluminum has a higher first ionization energy than sodium. This is because aluminum is located further to the right in the periodic table, where elements generally have higher ionization energies due to increased nuclear charge and the effective nuclear attraction on electrons. Sodium, being an alkali metal, has a lower ionization energy as it has a single electron in its outer shell that is more easily removed.
Successive ionization energies are the amount of energy required to remove an electron from an atom. Core electrons are closer to the nucleus and have higher ionization energies compared to valence electrons. By analyzing the ionization energy pattern, we can determine the number of core and valence electrons in an atom.

Fluorine. Ionization energies are a periodic trend and they generally increase as you go up and to the right in the periodic table.See the chart in the Web Links to the left for a complete chart of the ionization energies of all the elements.

No, the ionization energies of oxygen and xenon are not the same. Xenon has higher ionization energy compared to oxygen due to the increased number of electrons and stronger electron-electron repulsion in xenon.
Halogens
Ionization energies decrease moving down a group, because the shielding effect reduces the pull of the nucleus on valence electrons. Making them easier to remove.
The noble gases such as helium, neon, argon, and xenon typically have the highest ionization energies on the periodic table. This is because they have a full valence shell of electrons which makes it difficult to remove an electron.

The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.
