Hey guys, I have been struggling alot with the concept of ionization trends this is a question from an old practice exam my teacher gave.

Which of the following statements is/are true regarding first ionization energy trends?

i. oxygen has a lower ionization energy then fluorine
ii.nitrogen has a higher ionization energy than oxygen
iii. berryllium has a lower ionization energy than boron

a. i only
b. ii only
c. i and ii
e. i and iii

I think the answer is e. but I dont have the answer for this exam.

Also I wanted to know if any of you guys have any practice exams or such with questions having to do with ionization energy. I want to get as much practice as possible

All the best

A little hint will be also consider the electron configurations of oxygen, nitrogen, and beryllium.
