Pes worksheet. Pes and the submission of fitness reports of sergeants through major general as required by article 1129 of reference a and paragraph 25003 of reference b. What does this tell us about the relative number of electrons represented by each. Data from pes experiments are displayed as follows. Below is a photoelectron spectrum for the element phosphorus.
Pes is a method used to identify the placement of electrons for a single atom. The electrons are collected and their energy is analyzed. Refer to the pes spectrum below. In the diagram below the x axis is labeled high to low energies so that you think about the xy intersect as being the nucleus.
Thetriplepoint 2014 15 photoelectron spectroscopy electron configuration 4. Photoelectron spectroscopy pes is a technique that is used to gather information about the electrons in an atom. Photoelectron spectrophotometers use high energy radiation uv or x rays to eject electrons from an atom the photoelectron spectrophotometer inputs only one type of radiation with a specific energy because electrons within an atom are in different energy levels different electrons can require different amounts of energy to. Make note of the relative energies of each peak.
Some of the photons are absorbed and electrons are emitted. Pes spectra the photoelectron spectrum is a plot of the relative number of electrons emitted versus their ionization energy. Hotoelectron spectroscopy electron configuration 1. How do the peak heights compare.
Note that these are ionization energies for different electrons in the same atom.
