Atomic Structure Files

• Nuclear Chemistry Serveral Word and Rich text documents, author Chris Diehl, with graphics and data about nuclear reactions and reactors.
• Atomic Structure Activities  A WordPerfect Document, author John Eix, describing a series of historical dry labs that help the students develop an electron energy level model of the atom
• Atomic Structure Manual  A Word document, author John Eix, that describes the content related to the topic of Atomic Structure along with practice exercises.
• Flame Colours & Emmission Spectra  A Word document, author John Eix, describing a flame colour lab and observations of emission spectra from discharge tubes.
• Measurement of Ionization Energy Activity  A Word document, author John Eix, describing the measurement of ionization energies. Students then use the data to develop an energy level model for the atom, use the energy level graphs they produce to predict the 2s and 2p energy levels for Helium, then they predict the energy gap and associated spectral lines and compare with what they see with a diffraction grating spectroscope and a discharge tube of helium.
• Ionization Energy Spreadsheet TE  An Excel spreadsheet, author John Eix, showing calculations and graphs related to the "Measurement of Ionization Energy Activity", this is the teacher's edition.
• Ionization Energy Spreadsheet SE  An Excel spreadsheet, author John Eix, for the "Measurement of Ionization Energy Activity, this is the student's edition.
• Power Point Presentation - Energy Level Model (2003) A Power Point presentaion given at ChemEd 2003 in Auburn, author John Eix, showing how to create an electron model of an atom using ionization energies, making a quantitative prediction and valaidating that prediction.
• Power Point Presentation in PDF format - Energy Level Model (2003) A Power Point presentaion given at ChemEd 2003 in Auburn, author John Eix, showing how to create an electron model of an atom using ionization energies, making a quantitative prediction and valaidating that prediction in PDF format for those who do not have Power Point.
• Electron Model of the Atom (2003)  A PDF file, author John Eix, describing a one period activity guiding students to develop an electron model of the atom using successive ionization energies.
• Create Electron Model - Self Tutorial  A Zip file including a Power Point presentation and Excel files, author John Eix, you follow instructions in a Power Point presentation to take successive ionization energies stored in an Excel spreadheet, develop an energy level model for atoms, predict an electron jump for Helium and then test your prediction by observing the emission spectrum of Helium. These files were first used at BCCE 2006.
• Atomic Theory and Application Five Word documents in a ZIP file, author Bettyann Howson, the five files describe an emmission spectroscopy lab and additional ice cream recipes the other documents help students gain familiarity with the background knowledge of atomic theory and an application to a well known toxic chemical DHMO.
• A Digital Analogy for Light Phenomena  A Word document, author John S. Jones, describing an attempt to explain absorption spectra, emission spectra, the photoelectric effect, and the Bohr atom using a simple analogy for the behavior of light.
• Electron Configurations of Transition Metal Ions and Paramagnetism  A Word document, author Chuck Malerich, describing an activity where paramagnetism will be used to study whether transition metals form ions by losing higher energy, smaller orbital "d" electrons first or by losing lower energy, larger orbital "s" electrons.
• Photoelectric Effect  The download is a Word Document, author Charles Malerich, Chuck describes a circuit and method for building a simple light meter and an activity using different light sensors to demonstrate the Photoelectric Effect.
• Talking About the History of the Atom A Word Document, author Kara Pezzi, that describes a group project about the people who contributed to our understanding of atomic structure. Students verbally share clues and do research outside of class to match names, dates and contributions to create a timeline of atomic structure history.
• Coinium a New Element  The Download is a ZIP File of 2 Word Documents, author Evan Richards, describing both student and teacher's Guide versions of an isotope activity using conium.
• Illustrating Electrons (2003)  Five RTF and Word files, author Whitson, describing student sheets and teacher notes for two activities; magnetism and electron configuration, and flame tests.
