What Are Half Equations
In this video, we will learn how to write half equations for simple redox reactions. A half-equation shows what happens at one of the electrodes during electrolysis, so we need to be able to complete and balance half-equations for these...

Discovering the Sun's Mysteriously Hot Atmosphere
Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface. Temperatures in the corona — the Sun’s outer atmosphere — spike to 3...

NASA | Terrestrial Gamma-ray Flashes Create Antimatter
NASA's Fermi Gamma-ray Space Telescope has detected beams of antimatter launched by thunderstorms. Acting like enormous particle accelerators, the storms can emit gamma-ray flashes, called TGFs, and high-energy electrons and positrons....

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...

Practice Problem: Ionization Energy
When we learned about periodic trends, we learned about ionization energy. Just how much energy is required to remove an electron from an atom? What about a second electron, or a third? Let's compare a few different ionizations and see...
