The electron configuration of 1s 2 2s 2 2p 3 makes the element N. Photoelectron spectroscopy, usually abbreviated PES, is a lab technique that involves shooting an intense beam of radiation at a sample of an element and measuring the energy of the electrons that Photoelectron spectroscopy involves the measurement of kinetic energy of photoelectrons to determine the binding energy, intensity and angular distributions of these electrons and use the information obtained to examine the electronic structure of molecules. Photoelectron spectroscopy is based upon a single photon in/electron out process and from many viewpoints this underlying process is a much simpler phenomenon than the Auger process. The energy of a photon of all types of electromagnetic radiation is given by the Einstein relation : (5.3.1) E = h ν The full electron configuration of 6P is.. 21s 22s2p3s3p3 # protons = 15 # electrons= 15 The full electron configuration of 2S is.. 61s2s22p3s23p4 # protons = 16 # electrons= 16 29.

Photoelectron spectroscopy and electron configuration

If an electron is said to occupy an energy level in an atom then each electron must be in an orbital at a particular distance from the nucleus and the energy levels corresponding to these orbitals have a certain energy level. The next step in the location of the electron required Photoelectron Spectroscopy.

Specific attention is g •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 eject If an electron is said to occupy an energy level in an atom then each electron must be in an orbital at a particular distance from the nucleus and the energy levels corresponding to these orbitals have a certain energy level.
