Gen Chem - kaplan book confusion

[Blue39*]

I was reading through the Gen chem Kaplan book and in chapter 2 they discuss electron affinity, ionization energy, etc. However, a key concept bubble states that Fluorine has the highest ionization energy, and highest electron affinity. A chart on the same page shows that chlorine has the highest electron affinity because fluorine is incredibly tiny and unstable. I also thought that Helium had the highest ionization energy, but maybe it doesn't count the noble gases? If anyone could clarify what the MCAT wants me to know that would be great.

Yea I don't think they're counting NGs

Chlorine does have the highest electron affinity despite fluorine being the most electronegative/highest ionization energy (not counting noble gases). If I remember correctly, fluorine has quirky P orbitals that are relatively unstable due to electron repulsion
