Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Errata and notes:
1. I got the Oxidising Agent and the Reducing Agent the wrong way around! Sodium is the Reducing agent and Chlorine is the Oxidising agent. My confusion was that when a sodium atom looses an electron it becomes oxidised, so in my simple brain, I called it the oxidising agent. That is wrong because the agent that oxidises the sodium is the chlorine atom and so the labels are the wrong way around. Doh!
2. I drew the hydrogen H2 molecule with a double bond but it should be a single bond because they are bonded with a single covalent bond.
3. Where I have drawn carbon dioxide, the carbon should have a double bond to each of the oxygens.
4. Apparently Feynman diagrams are not that useful for theoretical chemistry, so perhaps that wasn't the best choice for the illustration. The feedback in the comments from a real theoretical chemist is "All we deal with is shuffling around electrons, but many many many electrons, so a Feynman diagram would need to be huge but at the same time would be very very repetitive."
5. In analytical chemistry, I should have called it distillation rather than precipitation.
6. My definition of organic chemistry being about ‘life’ is not very good. I should have said that organic chemistry looks at compounds that contain carbon. But there are some compounds in inorganic chemistry that also contain carbon, like carbon dioxide so I guess I'd also have to state that inorganic chemistry is almost everything else.
7. I said that fuels are inorganic chemistry which is misleading when I drew a car next to it. My understanding is that there are inorganic fuels that don't contain carbon, but obviously all the fuels we are familiar with are organic. I thought a picture of a car would tie a few things together elegantly, but it ended up giving the wrong impression. That’s okay, I’m still learning! :D
8. In inorganic chemistry, I should have stated that all natural minerals fall under inorganic chemistry so as not to be misleading, otherwise you might go way thinking that only man-made substances fall under inorganic chemistry which is not true. I said that 'a lot of the inorganic compounds that are studied are man-made' meaning that the cutting edge of research is mostly man-made substances.
9. Apparently water is not the most inflammable substance. I thought it was so that is interesting.
10. In the bonding section, hydrogen bonding and van der waals forces are technically inter molecular forces.

Chad gives a comprehensive lesson on how to rank acids and bases. This is presented in the context of the ARIO mnemonic which stands for Atom, Resonance, Induction, and Orbitals which helps students remember the most important factors affecting acidity and basicity in the most common order of importance. The Atom Rule for ranking acids and bases shows how the size and electronegativity of the basic atom affect its strength as a base. Of second importance is the effect of resonance on acidity and basicity as resonance can stabilize a base resulting in a weaker base. Typically of third importance is the effect of induction on acidity and basicity. Electron-withdrawing groups such as electronegative atoms near the atom acting as a base will help stabilize it resulting in a weaker base. Finally, the Orbital Rule describes the role that the hybridization of the atom acting as a base affects its basicity. Generally and all else being equal the order of stability with regard to hybridization is sp / sp2 / sp3 and the order of base strength is the opposite: sp3 / sp2 / sp. Chad provides numerous examples of how to rank acids and bases to demonstrate how each rule is applied, and concludes the lesson with several additional examples of ranking acids.
