The binding energy of the first level in an atom is 2.2*10^-¹⁸ J, and the binding energy of the second energy level is 1.6*10^-¹⁸ J. What is the energy of the photon that is emitted if an electron moves from the second level to the first? A) 3.3*10^-18 J B) 3.5*10^-36 J C) 1.4 J D) 3.5*10^-18 J E) 6.0*10^-19 J

Question

Quizplus · Accepted Answer

The energy of the photon emitted is the difference in binding energies: 2.2*10^-18 J - 1.6*10^-18 J = 6.0*10^-19 J.
