I think we can say that no, it doesn't make much sense from a human perspective.
Sodium and potassium are both extremely reactive when in their pure form, already as solid. Even worse, they react very energetically with water, releasing a lot of heat, to the point that a chip of sodium or potassium put in water float above a thin layer of water vapor and produces a lot sparkles.
Having an atmosphere of those two nasty atoms would make the requirements for the spacesuits even more severe, because they'd need to be resistant also to those aggressive atoms, which even worse would need to be at fairly high temperature to not condensate into a solid.
That said, an atmosphere makes sense if all the chain reactions happening from impact with cosmic rays and particles happen far away from the inhabited surface, so that most of the energy is dissipated where it doesn't hurt, which means that a too thin atmosphere could be even worse than no atmosphere, because it would act as a multiplier or the particles due to the above said impacts.
