I was having trouble with some lab question on atomic emission
spectra.
Also answer the following questions about your observations: Are the lines present in the hydrogen spectrum the same lines predicted by the Bohr model the atom? Which lines, if any, are missing? Why might there be lines missing? Compare the spectral lines from your unknown substance to the other spectra you observed. Based on these comparisons, what is the identity of the unknown substance? Are there any general...

05 Question (4 points) When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. AE...

1. The energy of the electron in the lowest level of the hydrogen atom (n=1) is -2.179×10-18 J. What is the energy of the electron in level n=5? -8.716×10-20 J (Answer is correct) 2. The electron in a hydrogen atom moves from level n=4 to level n=1. Is a photon emitted or absorbed? What is the wavelength of the photon? 3. An excited hydrogen atom emits a photon with a wavelength of 102.6 nm. In what region of the spectrum...

Name Lab Day circled: Mon. Tues. AM Tues, PM Wed Thurs. Fri. Prelaboratory Exercise for the Atomic Emission and Absorption Experiment The spectroscopes used in our lab are scaled in nanometer units. You will work with three of the four possible Balmer series transitions of Hydrogen whose lines are in the visible region of the electromagnetie spectrum. Electrons absorb energy from n-2 level and depending on how much energy is absorbed, they are excited to different higher energy levels. From...

5. A wave function for an electron in an atom is called an atomic orbital; this atomic orbital describes a region of space in which there is a high probability of finding the electron. Energy changes within an atom are the result of an electron changing from a wave pattern with one energy to a wave pattern with a different energy (usually accompanied by the absorption or emission of a photon of light). Each electron in an atom is described...
