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 electro transitions can start in a p orbital (I = 1) of n = 2 or higher, not in an s (I= 0) or d (1 = 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)? Check all of the allowed transitions: 3s → 2s 3s — 2р Зр — 2s Зр — 2р За — 2s 3d - - 2p 4s → 2s 4s > 2p
