A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and...

One could say that snowflakes are simply frozen water — but if you compare a snowflake to an ice cube, you’ll notice a big difference. Why are all snowflakes six-sided? Why are none of them exactly the same? And how do we ski on them?...

In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...

In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons...

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...

Coulomb’s Law is one of the most important laws when it comes to atomic structure and being able to understand and explain atomic properties. It helps to relate the force between two charged particles and can be represented by the...

This video describes the basic role that atoms play in creating electrical charges, as well as the nature and creation of static electricity. Various methods of charging are discussed, emphasizing the role that insulators and conductors...

The video explains how objects can become charged by the transfer of electrons, resulting in static electricity. It also discusses how charged objects exert non-contact forces on each other, with like charges repelling and opposite...

Upon viewing the Magnets and Electromagnets video series, students will be able to do the following: Define a magnet as a material that attracts iron and materials containing iron. Explain that magnets have a north pole and a south pole...

This video explains the concept of electric charge and how it can be transferred through friction. It demonstrates how a balloon, when rubbed against a person's head, gains a negative charge and attracts positive charges in the wall....

Determine the Hamiltonian for Multi-Electron Atoms #2 (Lithium)

Determine the Hamiltonian for Multi-Electron Atoms #1 (Helium)

Learn the basics about the shapes of simple molecules, when learning about properties of matter. In reality the shapes of simple molecules are 3-D molecules and should be visualised as such. Imagine now the central carbon atom surrounded...

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...

In this video, the teacher explains the behavior of protons and electrons when they come close to each other. They discuss how protons and electrons repel each other when they are of the same charge, but attract each other when they have...

What's the deal with electricity? Benjamin Franklin flies a kite one day and then all of a sudden you can charge your phone? There's a gap in conceptual understanding! Let's figure out what electricity is, exactly, and how it works.

The video is a lecture on forces, where the presenter introduces and discusses different categories of forces. The presenter explains what a force is, how it is defined, and how it arises from the interaction between two objects. The...

Real World Science: Force is one of a series of videos that encourages children to explore the world of science in their immediate surroundings. Through observation and experimentation, students will learn properties of forces, Newton's...
