10 cards from this deck
Energy to remove 1 mol eโe^-eโ from 1 mol gas atoms to +1+1+1 ions
Generally increases from Na to Ar
Increases (more protons)
No significant increase (same 3rd shell)
Decreases (eโe^-eโ pulled closer to nucleus)
Outer eโe^-eโ in p sub-shell (higher energy, more shielded)
Group 2: s sub-shell; Group 3: p sub-shell
p4p^4p4: 2 eโe^-eโ in same orbital repel, easier to remove
p4p^4p4: two eโe^-eโ paired in same p orbital
โ nuclear charge, โ atomic radius, similar shielding
