The Bohr Hydrogen Atom model We looked at this diagram for the Bohr model of the hydrogen atom. It shows the possible electron transitions between the various energy levels. Note: for this question, use computer style scientific notation with "E" and put + or - in front of the exponent, for example, \( 100.0=1.000 \mathrm{E}+2 \) Bohr energy Levels: \( \mathrm{E}_{\mathrm{n}}=-Z^{2}(13.6 \mathrm{eV}) / \mathrm{n}^{2} \) Energy change in a transition from one level to another: \( E_{\text {final }}-E_{\text {initial }}=-Z^{2}(13.6 \mathrm{eV})\left(1 / \mathrm{n}_{\text {final }}{ }^{2}-1 / \mathrm{n}_{\text {initial }}{ }^{2}\right) \)
Note: \( Z \) = atomic number; \( n \) = energy level number (1, 2, 3, etc.) Calculate the energy for \( n=5 \) Calculate the energy for \( n=2 \) Calculate the energy for the transition from \( n=5 \) to \( n=2 \) : \( \mathrm{eV} \) Convert this value from eV to J, using the conversion factor \( 1 \mathrm{eV}=1.602 \times 10^{-19} \mathrm{~J} \) J Let's start with the wavelength shown for this transition. What is the wavelength shown in the diagram? \( \mathrm{nm} \) What color of light is this? Calculate the corresponding frequency. (Recall that the speed of light, \( \mathrm{c}= \) wavelength \( \mathrm{x} \) frequency \( =2.998 \times 10^{8} \mathrm{~m} / \mathrm{s} \) ) frequency \( =\mathrm{cm} \) Using Planck's Law, calculate the energy of the corresponding photon of light. \( \mathrm{E}=h \times \) frequency where \( h \) (Planck's constant) \( =6.626 \times 10^{-34} \mathrm{Js} \) Energy = joules
Energy = joules Does the energy calculation from the observed wavelength agree with the prediction from the Bohr model? (fill in Yes or No)
