- 2 Select all that apply. Only certain electron transitions are allowed from one energy level to another. In one-electron species, the change in the quantum number I of an allowed transition must be ±1. For example, a 3p electron can drop directly to a 2s orbital but not to a 2p. Thus, in the UV series, where nfinal = 1, allowed electron transitions can start in a p orbital (I = 1) of n = 2 or higher, not in an s (1= 0) or d (l = 2) orbital of n = 2 or higher. From what orbital do each of the allowed electron transitions start for the first four emission lines in the visible series (nfinal = 2)?
