In photoelectron spectroscopy, an electron is ejected from an atom by the collision of a UV photon with
the surface of the atom. The equation describing this reaction is similar to the photoelectric effect described by
Einstein: hv = ½ mv + Ei, where E; is the ionization energy of the atom. In one experiment on potassium, the
kinetic energy of the ejected electron was 5.34 x 10ºJ when the UV source had a wavelength of 162 nm.
Calculate the ionization energy of potassium.

Why do hydrogen atoms emit bright lines of specific wavelengths rather than a continuous spectrum?arrow_forwardOzone in the stratosphere absorbs ultraviolet light of wavelengths shorter than 320 nm, thus filtering out the most energetic radiation from sunlight. During this absorption, an ozone molecule absorbs a photon, which breaks an oxygen-oxygen bond, yielding an oxygen molecule and an oxygen atom: O3(g)+hvO2(g)+O(g) (Here, hv denotes a photon.) Suppose a flask of ozone is irradiated with a pulse of UV light of wavelength 275 nm. Assuming that each photon of this pulse that is absorbed breaks up one ozone molecule, calculate the energy absorbed per mole of O2 produced, giving the answer in kJ/mol.arrow_forward
- 6.11 Define the term photon.arrow_forward6.103 Atomic absorption spectroscopy is based on the atomic spectra of the elements being studied. It can be used to determine the impurities in a metal sample. If an element is present, light at the appropriate wavelength is absorbed. You are working with a metal stamping company and the rolled steel you use to form panels for automobile doors is failing at an alarming rate. There is some chance that the problem is unacceptably high levels of manganese in the steel. Given that the atomic spectrum of manganese has three lines near 403 nm, how could you use a spectrometer to determine the amount of manganese in the steel?arrow_forwarddescribe waves in terms of frequency, wavelength, and amplitude.arrow_forward
- 1) Energy dispersive x-ray spectroscopy (EDX) is a commonly used characterization technique in Materials Science to determine the elemental composition of materials. To do this, EDX measures the emitted characteristic x-rays from materials (e.g. Ka), generated due to the excitation of electrons from a lower energy shell to a higher energy one. Assume that you are working as a Materials Engineer in a company that produces cars. Your company has purchased 1 ton of Cr-Fe-Cu alloy to fabricate a certain part of the car. Your boss asks you to determine whether the material your company purchased is, in fact Cr-Fe-Cu alloy. If it there is another element present in the material, you will return the purchased material and stop production. So, you perform EDX analysis on your material and you see that three x-ray energies are detected: 5416, 6406 and 8050 eV. Determine which elements are present in your material and decide whether you should send the purchased material back or continue…arrow_forwardCalculate the energy (in joules) of (a) a photon with a wavelength of 5.00 × 104nm (infrared region) and (b) a photon with a wavelength of 52 nm (ultraviolet region).
