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.

I give you 2 hints:

electronic configuration
Ar: 2.8
K+: 2.8
Ca2+: 2.8

Number of Protons:
Ar: 18
K+: 19
Ca2+: 20

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