From Ar, K+ and Ca2+
Why does Ca2+ have the largest Ionization energy??

isnt it obvious?
you are trying to remove an electron from a postively-charged particle.

hi,
Yes it is obvious, but what is the reason...K+ is also a positively charged ion isn't it? I'm just a bit confused.

tHANKS
I was also thinking the reason would be because Ca2+ has the most number of protons
