  Simulation: Periodic Trends II: Electron Affinity, Atomic Radius & Ionic Radius Mark as Favorite (0 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.

• 

  Trends of the Periodic Table, Atomic Radius, Ionic Radius, Ionization Energy, Valence Electrons | Middle School, High School

  Simulation: Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius Mark as Favorite (0 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.
