Chapter 10 Modern Atomic Theory and the Periodic Table

Max Planck energy quantathe energy is never emitted in a continuousstream but only in small discrete packets calledquantaelectrons are only in several energy levelshydrogen atom absorbs one or more quanta ofenergy, the electron will jump to a higher energylevelground state– the lowest energy levelexcited states– the higher energy levelswhen an electron falls from a high-energy levelto a lower one, a quantum of energy is emittedas light at a specific frequencyBohr model1) suggesting quantized energy levels for electrons2) showing that spectral lines result from theradiation of small increments of energy whenelectrons shift from one energy level to anotherhowever, Bohr model only succeeded in H atom,5did not succeed for heavier atoms
