Classroom Resources: Atomic Structure

1 – 4 of 4 Classroom Resources

• 

  Atoms, Model of the Atom, Atomic Theory, Matter, Elements, History, Introduction, Periodic Table | Middle School, High School

  Animation: Atoms: The Building Blocks of Matter Animation

  This animation explores the idea that everything is made of atoms, and that since atoms are so extremely small, even small objects contain vast numbers of atoms. Students will see several examples to illustrate this point. Then they will be given a brief overview of the evolution of how people thought about atoms from the ancient Greeks through Dalton. This animation was featured in the May 2022 issue of Chemistry Solutions. **This video has no audio**

• 

  Isotopes, Atomic Mass, Subatomic Particles | Middle School, High School

  Simulation: Isotopes & Calculating Average Atomic Mass

  In the May 2017 simulation, students first learn how the average atomic mass is determined through a tutorial based on the isotope abundance for Carbon. Students will then interact within a workspace where they will select the number of isotopes, the mass of each isotope as well as their abundancies in order to successfully build a mystery element. Finally they will use their choices to calculate the average atomic mass of the mystery element.

• 

  Atomic Radius, Ionic Radius, Electrons, Model of the Atom, Subatomic Particles, Periodic Table | Elementary School, Middle School, High School

  Animation: Atomic & Ionic Radii Animation

  This animation explores patterns in atomic and ionic radii. Students will look at the different sizes of atoms in the third period and the atoms in the sixth group to see trends across periods and down groups. They will also look at an atom and its corresponding cation as well as an atom and its corresponding anion. **This video has no audio**

• 

  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.
