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**
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**
