Why does K have a larger atomic radius than Na? The valence electrons in Na feel a stornger effective nuclear charge than those in K. The valence electrons in K feel a stronger effective nuclear charge than those in Na. OK is lower down the group than Na. The valence electrons in Na and K feel a similar Zeff. Those in K are in a higher energy level. The valence electrons in Na and K feel a similar Zeff. Those in Na are in a higher energy level.
