The figure below shows the first ionization energies for elements in the second row of the periodic table. Although there is a general trend toward an increase in the first ionization energy as we go from left to right across this row, there are two minor inversions in this pattern.

The ionization energy is the amount of energy needed to strip an electron off of an atom , ion, or molecule. The illustration shows that the metals like lithium, Li, and cesium, Cs, have relatively low ionization energies.

Those two factors account for the zigzag nature of the increase in ionization energy. Nevertheless, as a general trend, from left to right across the periodic table, ionization energy does increase. Also as you go down the periodic table, the ionization energy does decrease for the reasons given.

However, there are two variations on this basic trend. It is easier to remove an electron from a p orbital compared to an s orbital of the same quantum number. The p orbital is higher in energy, ... In going from nitrogen to oxygen there is a drop in the first ionization energy. This occurs because of the increased...
