TED-ED: Solid, liquid, gas and plasma? - Michael Murillo
Have you ever seen static electricity cause a spark of light? What is that spark? What about lightning, the Northern Lights, or the tail of a comet? All of those things and many others _ in fact, 99.9% of the universe -- are made of...

TED-Ed: Radioactivity: Expect the unexpected - Steve Weatherell
Neutrons don't change into protons. Except, sometimes, they do. Radioactivity is the process under which the nucleus can change spontaneously from one element to another. Steve Weatherell suggests that we acknowledge both the usefulness...

Inductive Effect Consequences: How Molecules React!
The inductive effect can drastically alter how molecules behave in reactions. Electron-withdrawing groups can increase a molecule’s electrophilicity, making it more likely to accept electrons in a reaction. Conversely, electron-donating...

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...

Practice Problem: Lattice Energy and Ionic Bond Strength
We know that within an ionic compound, the ions are held together by ionic bonds. What is the strength of those bonds, and what is the lattice energy possessed by the entire lattice? Can we compare two compounds and say which has the...

Acid-Base Equilibria and Buffer Solutions
Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.

Acids, Bases and Salts
It gives the definition for acids, bases and salts. It explains the litmus paper test to identify acids and bases. It discusses Arhenius concept of acids and bases.

Neutralization Reactions
We know about acids and bases, and we know about acid-base reactions, so what is a neutralization reaction?

Radioactivity: Expect the Unexpected
Several radioactive concepts are explained with the help of animated atoms, complete with their own facial expressions. As physical science pupils watch, they learn about gaining or losing atomic particles, alpha and beta particles, and...

Is Radiation Dangerous?
Not all radiation is hazardous. Electromagnetic radiation is pure energy. Nuclear radiation comes from the atomic nucleus in which isotopes become unstable and radioactive. Share this video with your class to explore the types of...

The pH Scale
The pH scale is actually based on logarithms rather than just simple numbers. The fact-filled video begins with an explanation of the auto-ionization of water. Then it describes the relationship between H+ and OH- in every solution. It...
