(a) The Ko X ray in a certain element has an energy of 8585 eV. Identify the elementby its atomic number.(b) The Kỵ X ray is emitted when an electron in the n = 2 shell makes a transition tofill a vacancy that has been created in the n = 1 shell. The KB X ray is emittedwhen an electron in the n = 3 shell makes a transition to fill a vacancy that hasbeen created in the n = 1 shell. Estimate the energy of the KB X ray in thiselement.
