Radioactive Isotopes, History, Subatomic Particles, Model of the Atom, Atomic Theory | Middle School, High School
Video: Ernest Rutherford Video
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.

Molecular Formula, Ionic Bonding, Covalent Bonding, Molecular Geometry, Naming Compounds, Lewis Structures, Periodic Table, Valence Electrons, Lewis Dot Diagrams, Ions, Subatomic Particles | High School, Middle School
Simulation: Ionic & Covalent Bonding
In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.

Simulation: Periodic Trends II: Electron Affinity, Atomic Radius & Ionic Radius
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
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.
