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 Mark as Favorite (28 Favorites)
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**

Pros Cons of Nuclear Power, Radiation, Radioactive Isotopes, Atomic Theory, Atoms, History | Middle School, High School
Video: Lise Meitner Video Mark as Favorite (29 Favorites)
This video tells the story of Lise Meitner, a pioneering female scientist in the field of nuclear chemistry, who was denied a Nobel Prize but has an Element named in her honor.
-
Atomic Theory, Electrons, Model of the Atom, Subatomic Particles, History | Elementary School, Middle School, High School
Video: Niels Bohr Video Mark as Favorite (68 Favorites)
This video tells the story of Niels Bohr, a great scientist who redefined how we think about atoms and the electron. Bohr’s model of the atom helped to advance understanding of subatomic particles, and holds an important place in the history and development of the atomic theory.
-
Atomic Radius, Ionic Radius, Electrons, Model of the Atom, Subatomic Particles, Periodic Table | Elementary School, Middle School, High School
Animation: Atomic & Ionic Radii Animation Mark as Favorite (70 Favorites)
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**
-
Model of the Atom, Electrons, Electron Configuration, Quantum Numbers, Subatomic Particles, Periodic Table | High School
Animation: Orbitals Animation Mark as Favorite (140 Favorites)
This animation explores the shapes of the 1s, 2s, 2p, 3s, 3p, 4s, and 3d orbitals and how they build up and overlap as each successive orbital is added. **This video has no audio**

Radioactive Isotopes, History, Subatomic Particles, Model of the Atom, Atomic Theory | Middle School, High School
Video: Ernest Rutherford Video Mark as Favorite (70 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.

Video: Dimitri Mendeleev Video Mark as Favorite (68 Favorites)
This video tells the story of how Dimitri Mendeleev organized the periodic table, even leaving gaps to be filled in with elements that weren't yet discovered.

Atomic Mass, Subatomic Particles | High School, Middle School, Elementary School
Video: History of the Periodic Table Video Mark as Favorite (123 Favorites)
In this video, Sam Kean tells the story of the development of the periodic table. He also pays tribute to each of the major scientific contributors, including Dimitri Mendeleev, who made great discoveries through their efforts to best organize the elements.
