Do we need to know the exceptions to the trends of Period Tables. Such as Oxygen has a lower ionization energy than Fluorine?
If so, could someone please help me with listing out which ones are we suppose to memorize?
Thank you!

I feel as if it would be wise to know which elements are exceptions the trends in the periodic table, especially if they are within the first 5 rows and could apply to any of the main topics like oxygen does. I would recommend checking Dr. Lavelle's lecture outlines and see if in any of them mention knowing the exceptions. There's nothing wrong with playing it safe by knowing them.
