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*0 ^- 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

The energy of the photon emitted is the difference in binding energies: 2.2 x 10^-18 J - 1.6 x 10^-18 J = 0.6 x 10^-18 J, which is 6.0 x 10^-19 J.
