Which has the larger atomic radius, S2-or K+? Both have the same electron configuration 1S22S22P63S23P6but I'm thinking that since K+has more protons, it would attract the electrons more, causing the electron cloud to be smaller - hence a smaller radius than S2-. Is this correct?
Understanding the structure, stability, and adhesion of solid-state battery interfaces has been significantly advanced by computational modeling techniques; a review of these key techniques follows. While the subject of this review is alkali metal solid-state batteries, its analysis of interfacial ...
