Looking at resonance structures for organic molecules and learning how to determine formal charge.

We are used to using a theory like VSEPR theory to predict molecular geometry, but unfortunately with coordination compounds, things are not so simple, because of those pesky d orbitals on the central metal atom. Crystal field theory is...

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

Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later...

It explains the Kossel-Lewis approach to chemical bonding, octet rule, covalent bond and classify its different types, Lewis dot structures of covalent compounds.

Overview of sublevels and shells in orbitals.

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!

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...

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...
