Examples of s-p Mixing in Molecular Orbital Theory
Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new...

Quantum Numbers, Atomic Orbitals, and Electron Configurations
Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD...

Filling of Orbital in Atoms
This nugget gives idea about Aufbau Principle, n+l rule, Pauli's Exclusion Principle and Hund's Rule.

Pseudo Noble Gas Electron Configurations
We've learned about electron configurations, and also about how this plays into ionization, given that elements will tend to ionize in such a way so as to achieve noble gas electron configuration. But certain transition metals will seek...
