Half Filled Orbitals

Postby Justin Vayakone 1C » Tue Nov 05, 2019 11:03 pm

So for number 9 in the Dino Nuggets Midterm Review, the UA's explained that oxygen actually has less ionization energy than nitrogen despite being on the right of nitrogen. I know it's because of half-filled orbitals being pretty stable, but does this concept apply to the periods below nitrogen and oxygen? For example, would phosphorus have more ionization energy than the element to the right of it which is sulfur? Also, does this half-filled concept disrupt the
left to right ionization energy trend in the d-block elements?

The trend holds true for most of the rest of the table and oxygen was the only exception that was highlighted, so I wouldn't worry about other exceptions or how oxygen affects elements around it. Just remember that it has a lower EN than nitrogen because of its half-filled p-orbital

Like the other student said, the trend is true for most of the elements except for Boron and Oxygen. Boron actually does have a lower IE in comparison to Beryllium and it is for a similar reason of Oxygen.
