The energy change for an electronic transition in a one-electron atom or ion (H, He+, Li2+, etc.) from n initial to n final is given by delta E = -(2.18 times 10-18 J)(Z2)(1/n2 final - 1/n2 initial), where Z is the atomic number. Which one o f the following species will have the longest wavelength emission line for the transition between the n initial = 2 and n final = 1 levels? O H O He+ O Li2+ O Be3+
O B4+
