Question

If a certain element being studied by x-ray photoelectron spectroscopy displays an emission spectrum with 6 distinct kinetic energies. What are all of the possible elements that could produce this spectrum?

Answer 1

In an atom, only two electrons can have n=3, Mp=2 Option (B) is correct. X-ray photoelectron spectroscopy is used to examine the electrons in care - levels using soft x-rays. Six distinct Kinetic energies mean six different electrons in different orbitals. Orbitals from which these lines are originating Is, 25, 2p , 35, 3p , 45 PES can be used to determine orbital energies directly. Each line corresponds to a different initial orbital energy. Elements that have electrons only in above orbitals to ave six different kinetic energies are : Ko Potassium: 18228²206 3 6²306 4S' Ca - Calcium: 18² 25² 2p6 38² 306 48²
