Question

If an electron in H-atom has an energy of -78.4k cal mol^-1. the orbit in which the electron prisent is....

Answer 1

is the amount of energy that an electron gains when subjected to a potential of 1 volt; 1 eV = 1.602 × 10–19 J. Using the Bohr model, determine the energy, in electron volts, of the photon produced when an electron in a hydrogen atom moves from the orbit with n = 5 to the orbit with n = 2.
