  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.

  Activity: Bohr Model vs. Quantum Mechanical Model Mark as Favorite (67 Favorites)

  In this activity, students will compare two models of the atom using cognitive scaffolding to move from the more simplistic Bohr model to the more abstract and accurate quantum mechanical model. They will examine experimental data and use it to explain periodic trends that cannot be accounted for with the Bohr model.

  Activity: Electron Configuration and Orbital Diagrams Mark as Favorite (68 Favorites)

  In this activity, students will learn how to apply the Aufbau principle, Pauli exclusion principle, and Hund’s rule to model electron configurations and orbital diagrams. They will use colored flat marbles to represent different directional spins of electrons as they fill orbitals based on energy level. They will then look for patterns in the electron configurations and orbital diagrams of various atoms and ions.

  Video: Ernest Rutherford Video Mark as Favorite (71 Favorites)

  Rutherford's initial research was studying alpha particles, which he hypothesized were helium nuclei. With the help of Hans Geiger, Rutherford conducted the gold foil experiment, which justifies that the nucleus of an atom is a dense collection of protons and contains the majority of an atom’s mass. It also inferred that most of the atom is empty space and electrons are not located in the nucleus. He won the Nobel Prize in chemistry in 1908 for his studies on radioactive substances.
