Solution: You may want to reference  (Page)  Chapter 12 while completing this problem.X-ray diffractometers often use metals that have had their core electrons excited as a source of X rays. Consider the 2p → 1s transition for copper, which is called the Kα transition. Calculate the wavelength of X rays (in angstroms) given off by the Kα transition if the energy given off by a mole of copper atoms is 7.77 × 105 kJ . (Note that 1Å = 10-10 m)
