Calculate the wavelength of the light emitted when an electron in a hydrogen atom makes each transition and indicate the region of the electromagnetic spectrum (infrared, visible, ultraviolet, etc.) where the light is found.
a. n = 2 → n = 1 b. n = 3 → n = 1
c. n = 4 → n = 2 d. n = 5 → n = 2
Solution Step 1 The balanced equations for the cases are as follows (a) Potassium metal is exposed to an atmosphere of chlorine gas. 2K (s) 2(g)2 KCl (s) (b)Strontium oxide is added to water SrO +(s) 2r((l) 2(aq) (c)A fresh surface of lithium metal is exposed to oxygen gas. 4Li +O 2Li O (s) 2 (g) 2 (s) (d)Sodium metal reacts with molten sulfur. 2Na +(s)Na(l) 2
