Content Videos (Lectures and animations to supplement lessons):

• History of the Atom
• Characteristics of the Atom
• The Periodic Table 1
• The Periodic Table 2
• Ion Formation
  • What are Ions?
  • Writing Electron Arrangement of Ions
  • Valence Electrons 1
  • Valence Electrons 2

Interactives (Online activities for student interaction & practice with content):

• The Atom (In this interactive activity from ChemThink, students learn about atomic structure. Follow the tutorial to understand how individual atoms—the basis of all matter—are composed of subatomic particles such as electrons, protons, and neutrons. Investigate the three types of particles, their properties (such as mass and charge), and relative locations)
• The Structure of an Atom (students examine atomic structure and the octet rule)
• Atomic Interactions Simulation (students explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the “Adjustable Attraction” atom to see how changing the parameters affects the interaction)
• Build a Molecule! Simulation (students start from atoms and see how many molecules they can build. Collect molecules and see them in 3D!)
• The Periodic Table
  • Chemical bonding of Elements
  • Periodic trends
  • Periodic trends in Electronegativity
• Ion Formation
  • Ions (students learn that ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in cations and in anions)
  • Names & Solubility of Ionic Compounds
  • Atomic Structure & Ionic Bonding (In this animated lesson, learners examine the chemistry behind table salt)
  • Ion Charges (In this interactive object, the learner practices identifying charges on ions)
  • Solubility of Ionic Compounds in Water (Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds)
  • Building Elements (students build up orbitals and electrons piece by piece in order to construct a given element)
  • Atomic Electron Configurations Simulation (students click on an element in the periodic table and see the electron configuration in the box/dash notation as well as the noble gas notation)
  • Writing Balanced Equations (students use this interactive tutorial to learn the fundamentals of balancing chemical equations)

Games (Online games for students to apply & test their content knowledge):

• Build an Atom (Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!)
• Atomic Structure Quiz
• ChemGameTutor: Atomic Theory (Dr. Despair has captured the top 12 chemists of all time! Students must choose the “Atomic Theory” Level and use their knowledge to set them free!)
• Name That Atom! (students test their knowledge about the Atom)
• Basic Atomic Structure Game (timed labeling game)
• Gridlock: Atomic Structure (Gridlocks are a fun way to learn the facts you need in Chemistry. Unlock the grids to gain entry to the next level and a secure knowledge of the chemistry involved. Based on the ideas behind Su Doku, Gridlocks have a twist that makes them more interesting, more fun, and more useful)
