The absorption spectra of ions have been used to identify the presence of the elements in the atmospheres of the sun and other stars. What is the energy of a photon (in J) that is absorbed by He+ ions, when an electron is excited from the Bohr orbit with n = 1 to the n = 6 state? The energy of an electron in the nth level is? En= -BZ^2/N^2

Laboratory questions: Atomic Emission Spectra This sheet has to be returned with your lab report and placed at the annex section A one electron excited ion (not hydrogen) absorbs a green photon: 2 - 542 nm. The electron, initially at the Bohr energy level n=8, moves to the level n = 14 after the photon absorption. Identify this ion (hint: find the Z value).
Bohr model of an atom In the Bohr model of an atom (see figure below) the electrons move on fixed circular orbits around the nucleus. On the th orbit the magnitude of the angular momentum of the electron is given by where ћ 6.626 x 10-34 m 2 kg/s is the reduced Planck constant. +Ze (a) Calculate the radius r of an electron orbit in the hydrogen atom. Express your answer in terms of n, ћ, co, the electron charge...
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...
Bohr Model - Line Spectra 2 -0.07.ww Bohr's Model - Line Spectrum in eV:E, --13.6.1-1.2.3.4. SE-EE Emitted lines Electrons in hydrogen atoms are in the n = 7 state (orbit). They can jump up to higher orbits or down to lower orbits. Emitted Spectral lines: When electrons in the higher orbits (with higher energies) jump DOWN to Lower orbits (with lower energies), energies are emitted in the form of emitted photons (light). The electrons jump from n = 7 state...
