Well, noble gases such as Helium, Neon and Argon have an electron affinity nearly zero because they have octet configuration. Due to this reason , they find it hard to attaract electrons. However higher members of Group 18 in the periodic table such Xenon, krypton and radon, do form compound like XeO2 and XeO4 due to the presence of vacant d- orbitals.
i am only a class 10 student. please reply if my answer was good enough.

Hope it's help u

hey guys, quick question on Period 3 elements and the Electron affinity

i know that electron affinity increases across period 3 because
1. the radius slightly decreses while the nuclear charge increases and so the atom reaches maximum stability

however, in data tables the electron affinity (ini kJ/mol) goes like this
Na = 53
Mg = 0
Al = 42
Si = 134
P = 72
S = 200
Cl = 349
Ar = 0

So if the affinity increases, then why does the data show that actually, it varies across the period??
Thanks for any help, it is much appreciated!
