Ions with a single electron such as , He⁺ , Li²⁺ and Be³⁺ are described by the H atom wave functions with Z a₀ substituted for 1/a₀, where Z is the nuclear charge. The 1s wave function becomes . Using this result, compare the mean value of the radius at which you would find the 1s electron in H, He⁺, Li²⁺ , and Be³⁺
