Periodic Trends
Are there any exceptions (of elements) that we will have to know that do not follow the general trends of electronegativity/ electron affinity?

No, there are no exceptions. However just remember that the most electronegative is F>O>Cl>N

I don't think so. I believe that that rule is applicable to all elements in the periodic table.

No, there is no exceptions to the periodic trends. There are exceptions though to things like how the orbitals are filled.

Electronegativity increases to the right, but this trend does not include the noble gases. So Fluorine has the highest electronegativity, not Ne or He. This makes sense because electronegativity refers to an element's ability to form covalent bonds, and noble gases don't bond.

*remember that there are exceptions for other trends like ionization! For example, Nitrogen is higher than Oxygen for first ionization energy!

Can someone please explain how oxygen has a higher electronegativity that chlorine when chlorine is a halogen and should want electrons more than oxygen?
