in a hydrogen atom. 8. Using the Bohr model, determine the wavelength when an electron in n=1 is excited to n = 3. 9. How are the Bohr model and the quantum mechanical model of the hydrogen atom similar? How are they different? 10. What are the allowed values for each of the four quantum numbers: n, l, m, and m?
4.66 Explain how the Bohr model of the atom accounts for the existence of atomic line spectra. 167 TATI. . 4.72 In order for hydrogen atoms to give off continuous spectra, what would have to be true? 4.56 It always takes energy to remove an electron from an atom, no matter what n shell the electron is in. Also, the higher the n, the more energy an electron starts out with (a) Explain why it takes energy to remove an...
You obtain spectra for two galaxies and measure the observed wavelength of a hydrogen emission line that has a rest wavelength of 656.3 nm. Here are your results: Galaxy 1: Observed wavelength of hydrogen line is 672.9 nm Galaxy 2: Observed wavelength of hydrogen line is 692.6 nm (a) Calculate the redshift, z, for each of the two galaxies. (b) What is each one’s recessional velocity (in km/s)? (c) Which of these galaxies is farther away from you? (d) How...
According to the Bohr model, the energy of the hydrogen atom is given by the equation: E = (-21.7 x 10 -19 J)/ n 2 Calculate the wavelength of the photon emitted when the atom undergoes relaxation from the first excited state to the ground state The answer is 1.22 x 10-7 m but I don't know how ?
Consider the Bohr model for the hydrogen atom in its second excited state. How much energy would it take to ionize the atom? 13.6 eV More than 13.6 eV Less than 13.6 eV
Although the Bohr model was very successful in accounting for the line spectrum of hydrogen, from what limitations did it suffer? It failed to predict the line spectrum for multi-electron atoms. It incorrectly proposed that electrons could reside between orbital's. It only accurately predicted the visible series of lines in the line spectra of atoms, but not the ultraviolet or infrared series. It incorrectly proposed that electrons move in fixed, defined orbits. It did not explain the quantized nature of...
2. Using the Bohr Model of the hydrogen atom, calculate the wavelength, frequency, and energy of the Humphreys beta (n-8- spectral line. Would this spectral line be visible from the ground (you will have to investigate the transmission of the atmosphere)?
The hydrogen Balmer Hβ spectral line is caused by radiation absorbed or emitted as an electron transitions between the 1st excited state and the 3rd excited state in a hydrogen atom. a) Using the Bohr model, calculate the energy of the electron when it is in the 1st excited state, in units of electron-Volts (eV). b) Calculate the energy of the electron when it is in the 3rd excited states, in units of eV. c) Calculate the energy difference between...
which of the following statements about the quantum- mechanical model of atoms is true? a. not only did the bohr model correctly describe the hydrogen atom and its line spectra, but it also perfectly described more complicated multielectron atoms b. multiple measurements of the position of hydrogens electron, when its in the ground state, find a range of values, but on average, it is located at a distance of one bohr radius from the proton c. there are multiple values...
