  Emission Spectrum, Emission Spectrum, Electromagnetic Spectrum, Subatomic Particles, Electrons, Atoms, Atomic Theory, Model of the Atom | High School

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron Mark as Favorite (65 Favorites)

  This activity is designed for students to build a scientific argument about the relationship between energy and spectral lines by exploring how light interacts with atoms. In the process, students will examine proposed models of the hydrogen atom and use collected data to analyze the proposed models. They will then select one of the models and write a scientific argument to support their choice. Students will then review additional data to support and/or refute their selection. Based on their analysis, students will revise their selected model and construct a new argument to support their revisions.

  Electron Affinity, Atomic Radius, Ionic Radius, Ions, Atoms, Periodic Table, Model of the Atom, Subatomic Particles, Electrons, Valence Electrons | High School

  Simulation: Periodic Trends II: Electron Affinity, Atomic Radius & Ionic Radius Mark as Favorite (33 Favorites)

  The May 2016 simulation is a follow-up to the March 2016 simulation. Students will focus their investigation on the electron affinity of an atom. Through the use of this simulation students will have the opportunity to examine the formation of an anion as well as compare the atomic radius of a neutral atom to the ionic radius of its anion.

• 

  Atomic Radius, Ionic Radius, Ionization Energy, Valence Electrons, Periodic Table, Atoms, Electrons, Subatomic Particles, Ions, Model of the Atom | High School

  Simulation: Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius Mark as Favorite (100 Favorites)

  In this simulation for the March 2016 issue, students can investigate the periodic trends of atomic radius, ionization energy, and ionic radius. By choosing elements from the periodic table, atoms can be selected for a side by side comparison and analysis. Students can also attempt to ionize an atom by removing its valence electrons. Quantitative data is available for each periodic trend, and can be further examined in a graph.
