  1. Within a year Neils Bohr had a model of the hydrogen atom that "explained" the spectral lines. Bohr introduced a new concept, the energy level. The electron in hydrogen had certain allowed energy levels, and the sharp spectral lines were emitted when the electron jumped from one energy level to another.

  2. The Bohr model and Spectra. 1. The Bohr Theory of the atom states that electrons can only exist in specific energy levels. If an atom absorbs energy, its electrons are temporarily at a higher energy level and the atom is said to be in an excited state.

  3. Use the Bohr Model of the Hydrogen Atom and the Electromagnetic Spectrum in the reference tables to. answer the following questions: 1. When an electron in an excited state moves from n=6 to n=2, what wavelength of energy is emitted? What region of the EM spectrum is this wavelength located? 2.

  4. Bohrs model of the hydrogen atom, proposed by Niels Bohr in 1913, was the first quantum model that correctly explained the hydrogen emission spectrum. Bohr’s model combines the classical mechanics of planetary motion with the quantum concept of photons.

  5. Using the model described in the introduction, we are prepared to calculate some key features of the hydrogen atom and compare them with experimental measure- ments.

  6. THE BOHR MODEL AND SPECTROSCOPY OF THE HYDROGEN ATOM. OBJECTIVES . To perform calculations associated with the Bohr model of the hydrogen atom and compare the results to the observed spectrum of the hydrogen atom. MATERIALS. Solutions of metal salts. EQUIPMENT. Spectrometer; emission tubes of various elements. SAFETY.

  7. Strengths of the Bohr model of the atom 1. Bohrs model of the atom could explain the size of the hydrogen atom. The radius calculated corresponded to known values of the hydrogen atom. 2. Bohr’s model gave an ionization value (–E 1) that corresponded to the known ionization value for the hydrogen atom. 3.
