1) Energy dispersive x-ray spectroscopy (EDX) is a commonly used characterization technique in Materials Science to determine the elemental composition of materials. To do this, EDX measures the emitted characteristic x-rays from materials (e.g. Ka), generated due to the excitation of electrons from a lower energy shell to a higher energy one. Assume that you are working as a Materials Engineer in a company that produces cars. Your company has purchased 1 ton of Cr-Fe-Cu alloy to fabricate a certain part of the car. Your boss asks you to determine whether the material your company purchased is, in fact Cr-Fe-Cu alloy. If it there is another element present in the material, you will return the purchased material and stop production. So, you perform EDX analysis on your material and you see that three x-ray energies are detected: 5416, 6406 and 8050 eV. Determine which elements are present in your material and decide whether you should send the purchased material back or continue production.

The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explain…

Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
