An electron falls to the n= 1 energy level (i.e. nf =1) during a transition. The wavelength of the line emitted was 95 nm. Calculate the energy level the electron fell from (i.e. ni) to the nearest whole number. Calculate the energy of this line. 12. What is the difference in explanation between the quantum mechanical treatment of the electron in the atom and that from classical physics? 13. Based on quantum mechanics, the wave function of an atomic orbital has four quantum numbers. (a) What is the name and symbol of each of these quantum numbers? (b) Briefly explain which property of the atom each quantum number governs. (c) What are the permitted values for each quantum number? 14.
