The wave number of a spectral transition for a single-electron atom or ion with nuclear charge (atomic number) Z is given by: =Z2R() where R is the Rydberg constant. For this question use the value for hydrogen =1.097 x 107 m a. What wavelength of light would be required to excite an electron to the 4th energy level for a hydrogen atom initially in the ground state? [1.5 marks] (Give your answer in scientific notation to 3 significant figures. For example, if your answer was 2.31 x 10 you should enter 2.31e-6) m b. What wavelength of light would be required to excite an electron to the 4th energy level for a Li2+ ion initially in the ground state? [1.5 marks] (Give your answer in scientific notation to 3 significant figures. For example, if your answer was -2.31 x 10 you shou enter -2.31e-6) m The wave number of a spectral transition for a single-electron atom or ion with nuclear charge (atomic number) Z is given by: =Z2R() where R is the Rydberg constant.
