Quite the opposite really, moving down a group the general trend is 1st ionisation values tend to decrease; this is explained by the increase in the number of occupied energy levels causing an increase in atomic radius, therefore electrostatic attraction between valence electrons and the nucleus...

My main question is why is a full p sub-shell considered stable, whereas a full s sub-shell considered unstable and its electrons undergo e-e repulsion?

Doesn't it have to do with e-e repulsion?

I am fully aware that a half filled p sub-shell is stable due to no repulsion as electrons first occupy the orbitals singly before pairing up according to Hunds rule, why is that however a fully occupied p sub-shell with 6 electrons is also considered stable? Where as a filled s sub-shell with 2...
