Metallic Solids
In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance, malleability,...

Metallic Bonding
In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This sharing...

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress...

Atomic Models
In this video Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in...

That Time We Gave Earth a Ring Made of Millions of Tiny Needles
In the 1960s, the USA almost put a ring around the Earth by launching hundreds of millions of tiny copper needles into space in an attempt to create a reliable boost for their communications systems.

Chemical Bonds: Covalent vs. Ionic
Mr. Andersen shows you how to determine if a bond is nonpolar covalent, polar covalent, or ionc.

A Tour of the Periodic Table
Mr. Andersen describes the major groups on the periodic table.

MAGNETS - How Do They Work
How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Series and Parallel Circuits
Mr. Andersen contrasts series and parallel electrical circuits. A simulation is used to visualize electron flow through both circuit types.

Quantum Mechanical Model
In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

The only isotope video you need to watch
Isotopes are just different atoms that represent the same element but have a different mass. In this video, students will learn what is an isotope and how to tell the difference between isotopes of different atoms. This video will make...

Drawing Bohr Models of Atoms and Ions - 3 easy steps!
While While the Bohr model of the atom is not the most accurate model we have today, it can help up show a lot of valuable information about the atom. Bohr models can show the protons and neutrons in the nucleus along with the number of...

Why do covalent compounds share electrons?
A covalent compound forms when electrons are shared and this will happen when you have 2 nonmetals, or 2 anions, bonding together. The reason these elements share their electrons is because they have a small difference in...

Determining the Number of protons, neutrons and electrons in an ATOM
In this video, we're going to learn about the number of p, n and e in an atom. We'll explore the atomic structure of different elements, and see how the number of protons, neutrons and electrons affects the properties of those elements....
