Electrons DO NOT Spin
Quantum mechanics has a lot of weird stuff - but there’s thing that everyone agrees that no one understands. I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the...

Ionic Bonding
In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

Periodicity
In this video Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri...

Electron Configuration
In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and...

What Atoms Really Look Like: The Quantum Model Explained
When Ernest Rutherford realized that atoms have a heavy nucleus, he hypothesized that the way the moon orbits earth is the same as the way an electron orbits the nucleus of atoms. We now know an atom would not look anything like this. So...

Pauli's Exclusion Principle: The rule of electrons
Wolfgang Pauli's Exclusion Principle, developed in 1925, is a crucial concept in quantum mechanics. It states that two electrons in the same atom cannot have the same set of quantum numbers, which are the principal quantum number (𝑻n),...
