There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
The trend in period 2 ionization energy across the elements increases from left to right.
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
It decreases when going down a group.
Ionization energy would be similar.
The exception to the trend of increasing ionization energy across a period in the periodic table occurs when transitioning from group 2 to group 3 elements. This is because the group 3 elements have a slightly lower ionization energy compared to the group 2 elements due to the added stability of having a half-filled or fully-filled subshell.

I suppose that this trend is normal.
Noble gases have stable electron configurations with a full valence shell, so they have a high ionization energy. Their ionization energy values don't follow the typical trend due to their unique electron structure, which makes them less likely to lose or gain electrons easily compared to other elements.
It decreases when going down a group.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
The first ionization energy decreases because the outermost electron is farther from the nucleus. Apex

All of the elements on the top half of the periodic table belong in upperionizationenergy because the trend is top to bottom. Top being lowest and getting bigger as it goes down.------------------------------------------------------* In a group: the ionization energy decrease from the lighter elements to heavier elements.* In a period: the ionization energy increase from the left elements to the elements of the right.* When the atomic radius decrease the ionization energy increase.
The ionization energy increase from sodium to fluorine.
