Ionization Energy of Group 16

Postby AlyssaYeh_1B » Sun Nov 03, 2019 4:06 pm

If oxygen has a lower ionization energy than nitrogen, does that apply to all the other elements in group 16? As in, they will all have lower ionization energies compared to their neighbor to the left?

yes the order of increasing ionization energy is from bottom to top and then left to right, so Fluorine being the most electronegative. if you're reading it from right to left then the energies will decrease.

The general trend for ionization energy is that it increases as you move from left to right and decreases as you move from top to bottom. So elements in group 16 will have a higher ionization energy compared to elements on their left.

Terelium and polonium have higher first ionization energies than the elements next to them in group 15, but oxygen, sulfur, and selenium all have lower ionization energies than the elements to their left in group 15. This is because group 16 is the first time that there is a paired electron in the p orbital (the previous three elements have filled up the first three spots) so it has a smaller ionization energy.
