Which element in Group 18 of the Periodic Table has the highest lonization energy?

all the elements in group 18 are Nobel gases or inert gases . all the elements such as neon , helium, argon etc. ,their outermost shell is completely filled . The noble gases have the largest ionization energies, reflecting their chemical inertness

its going to be mutualism cuz they both benefit from the relationship.
