why is more energy required to remove one electron from a sodium atom than from a potassium atom.?
use electron configuration to explain.
I am confused. The two have their first highest shell in common, it has only one electron filled in it. So what is the reason? Thanks

Electrons are closer to the nucleus in the Na than in the K so there is more attraction, so it's harder to remove.

nicely metals react via loosing electrons, the two sodium and potassium have one electron of their outer shells. yet potassium has extra shells so the atomic radii is larger this suggests the electrons exchange into much less attracted to the protons of the atom so the electrons at the instant are not held as "tightly."
