What exceptions to the ionization trend are we expected to know?

Maybe the ones where we're able to work out from the periodic table?
Like the electron configuration of nitrogen is 1s2 2s2 2p3 (stable, half filled) while Oxygen has an electron configuration of 1s2 2s2 2p4 (one extra electron from being stably half filled), so taking an electron from the oxygen is "easier" (requires less energy) because it is more "willing to give the electron up".
