WebJan 6, 2024 · Niel Bohr’s Atomic Theory states that – an atom is like a planetary model where electrons were situated in discretely energized orbits. The atom would radiate a photon when an excited electron would … WebIt 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. Show your calculations.
WebVideo \(\PageIndex{1}\): An introduction to the Bohr Model of the Atom. In 1913, Niels Bohr attempted to resolve the atomic paradox by ignoring classical electromagnetism’s prediction that the orbiting electron in hydrogen would continuously emit light. Instead, he incorporated into the classical mechanics description of the atom Planck’s ideas of … WebSo, we have the energies for three different energy levels. The energy for the first energy level is equal to negative 13.6. E two is equal to negative 3.4, and E three is equal to negative 1.51 electron volts. So energy is quantized using the Bohr models, you can't have a value of energy in between those energies.
