WebA photon is emitted from the electronic structure of an atom when an electron A. jumps from a higher to a lower energy level. B. jumps from a lower to a higher level. C. reverses its spin by 180°. D. is removed from an atom by a high quantum of energy. a. jumps from a higher to a lower energy level WebIn 1913, the Danish scientist Niels Bohr suggested a reason why the hydrogen atom spectrum looked this way. He suggested that the electron in a hydrogen atom could not have any random energy, having only certain fixed values of energy that were indexed by the number n (the same n in the equation above and now called a quantum number 8 ).
WebWhen an electron moves from a higher-energy orbit to a more stable one, energy is emitted in the form of a photon. To move an electron from a stable orbit to a more excited one, a photon of energy must be absorbed. Using the Bohr model, we can calculate the energy of an electron and the radius of its orbit in any one-electron system. WebQuantum Photonics.
