Examine the energy-level diagram for hydrogen shown above, and answer the following questions:

(a) If an electron is in the n = 1 shell, what is the electron’s scaled energy in electronvolts?

(b) If an electron is in the n = 2 shell, what is the electron’s scaled energy in electronvolts?

(c) How much energy would it take to transfer an electron from the n = 1 shell to the n = 2 shell?

(d) Would it take the same, more, or less energy than your answer to (c) to take an electron from the n = 2 shell to the n = 3 shell? Why?
