In photoelectric absorption to dislodge an inner-shell electron from its atomic orbit,the incoming x-ray photon must be able to transfer a quantity of energy:

Question

Quizplus · Accepted Answer

In photoelectric absorption, the incoming x-ray photon interacts with an electron in the inner shell and transfers all its energy to dislodge the electron from its orbit. The amount of energy that binds the electron in its orbit is termed as the binding energy. Therefore, the incoming x-ray photon must transfer an amount of energy as large as or larger than the binding energy of the electron to dislodge it from its orbit. Hence, the correct option is C. Options A, B, and D are incorrect as they either imply that the incoming photon transfers an insufficient amount of energy or an unnecessarily large amount of energy.
