All hail RADIUS! If you want to understand why an atom does what it does, take a look at those outermost electrons (a.k.a. the valence electrons). You can look at how...

This is it! Here is the entire course IN ORDER!
Ionization energy is how difficult it is to remove an electron from an atom or an ion. Once you understand the radius trends, ionization energy isn’t that tough to...
So how do you tell how much an atom or ion wants an electron? It’s called affinity. It’s not that dissimilar to ionization energy, but in this case we are...
We’ve covered enough ground to get a different perspective on ions. Let’s refresh what we know about our charged friends by bringing in the concepts of...
How badly an atom wants an electron is always important, but doubly so in a chemical bond. For this will determine the actual nature of the chemical bond: ionic...
The great chemist, Gilbert N. Lewis created a simple way to show how atoms in compounds (typically covalent) bond with each other. The trick to keeping it simple was to...
So what happens when you run out of electrons in a Lewis Structure? You’re going to have to break out the double and triple bonds. And that is exactly where they...
Once you feel pretty good about the basics of Lewis Dot, you might want to dig a little deeper. Explore molecules with odd numbers of electrons, decide among multiple...
2D Lewis Dot structures are really handy, but not quite representative of the actual shape in the 3D world. With a little more work you can make those flat structures...
Ok, we’ve talked about Lewis Structures and we’ve talked about VSEPR. But wouldn’t it be nice if we could practice them together on the same molecules...
