Modern Atomic Theory: De Broglie’s, Schrodinger’s & Heisenberg’s Contributions
Is covering three giants of modern atomic theory in one ten minute video possible? Yes. Can it be done well? Probably not! But are you CERTAIN? Let’s find out.
Isaac Newton once said, “If I have seen farther than others, it is because I’ve stood on the shoulders of giants.” Niels Bohr easily qualifies as both...
Max Planck might be the most important physicist you’ve never heard of. We will do our best to help you understand his concept of quantized energy; a concept that...
If you want to understand modern atomic theory, you are about to engage in a Sisyphus-esque struggle against the weird yet true. To do this, we must first understand the...
One footnote to the whole stoichiometry thing is the concept of percent yields. Though you may theoretically predict a certain amount on paper, what you actually get can...
Life’s not perfect. You run out of milk for your cereal. There is no bread left for your sandwich. In real life, as in chemistry, we constantly deal with the...
So let’s take a look at a classic stoichiometry problem. We’ll start with grams of one substance in a chemical reaction and work through to the equivalent...
Stoichiometry is the ultimate tool of the chemistry student. Not unlike Daniel in the Karate Kid, you will take all of the disparate skills you’ve learned so far...

Composition Mathematics: Determining Molecular Formula From Percent Composition
You can find molar masses, percent compositions, and empirical formulas from those percent compositions. What’s left? Well, it’s one thing to determine the...
