Solved: The figure below represents part of the emission
Chapter , Problem 127(choose chapter or problem)
The figure below represents part of the emission spectrum for a oneelectron ion in the gas phase. All the lines result from electronic transitions from excited states to the n_3 state. (See Exercise 126.) Wavelength A B Mg1g2 _ 2F1g2 SMg2_1g2 _ 2F_1g2 Mg_1g2 _ F1g2 SMg2_1g2 _ F_1g2 Mg1g2 _ F1g2 SMg_1g2 _ F_1g2 Na1g2 _ Cl1g2 SNa_1g2 _ Cl_1g2 I4 _ 17,948 kJ/mol I3 _ 14,807 kJ/mol I2 _ 1752 kJ/mol I1 _ 896 kJ/mol a. What electronic transitions correspond to lines A and B? b. If the wavelength of line B is 142.5 nm, calculate the wavelength of line A.
