Compare the Bohr model of the atom with the Schrödinger's model. Explain how light interacts with matter to produce line spectrum. Calculate the relationship between wavelength and energy of a photon.
20 cze 2015 · The model we will describe here, due to Niels Bohr in 1913, is an early attempt to predict the allowed energies for single-electron atoms such as \(\ce{H}\), \(\ce{He^{+}}\), \(\ce{Li^{2+}}\), \(\ce{Be^{3+}}\), etc.
this lab you will use spectroscopy to evaluate the Bohr model for the hydrogen atom and to examine the line spectra of various elements. In the first two parts of this experiment, you will record emission spectrum of hydrogen atom and calculate the energy, wavelength and energy level, n i, of each transition in emission spectrum of hydrogen atom.
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.
24 lip 2024 · The simplest example of the Bohr Model is for the hydrogen atom (Z = 1) or for a hydrogen-like ion (Z > 1), in which a negatively charged electron orbits a small positively charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another.
How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.
Atoms of individual elements emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object. Niels Bohr explained the line spectrum of the hydrogen atom by assuming that the electron moved in circular orbits and that orbits with only certain radii were allowed.
