(a) The characteristic emission from Ca occurs at 422.7 nm and corresponds to an electron going from a 4p orbital to a 4s orbital. Calculate the energy of the electron in the 4p orbital. Calculate Zeff for the electron in the 4p orbital.
(b) The same 4p to 4s transition in potassium occurs at 769 nm. Calculate the energy of an electron in the 4p orbital of potassium and Zeff for this electron.
(c) Explain the differences between your answer to parts (a) and (b).
