There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
It decreases when going down a group.
It decreases when going down a group.
None of them do exactly. The elements' ionization energies definitely trend in a couple of ways though. The ionization energy variations tend to decrease as atomic number goes up and tend to increase as you remove more electrons from the atom.
The ionization energy increases going across a periodic table.This is because of increasing nuclear charge.
electronegativity and the first ionization energy both increase as you move up the periodic table.APEX
I suppose that this trend is normal.
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
It decreases when going down a group.
It decreases when going down a group.
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.
The ionization energy increases going across a periodic table.This is because of increasing nuclear charge.
The trend for first ionization energy
Electronegativity and first ionization energy both increase as you move up the periodic table
