- Please solve this question accurate, I'll appreciate and will rate it up thanksThe structure of an atom is analogous to a model of the solar system. Explain why this statement is true.Explain the process by which an energy dispersive X-ray spectrum (EDX) spectrum is generated and the origins of the La and Ka lines for Fe in the EDX shown in Figure 3 below. Why do the Fe La lines have a lower energy than the Ka lines? By considering the energy of the X-rays measured, discuss whether EDX can be used to measure whether the iron in an iron oxide is in 2+ or 3+ valence state? Which other spectroscopy technique in the transmission electron microscope (TEM) is more appropriate and why? OK 0.01 10.00 kev Figure 3: EDX spectrum of multi-element glass (NIST K309) containing 0, Al, Si, Ca, Ba and Fe.
