Chemistry, Atoms and Materials: The Best Science Videos on Elements, Bonds, and Matter
See our guides to the Periodic Table, Chemical Reactions, and Materials Science.
Why Atoms Behave the Way They Do
The whole of chemistry starts with a single question: why does each element act the way it does? The answer is hiding in the count of protons and the arrangement of electrons.
Why Does Changing Just One Proton Change an Element?
Add a single proton to a nucleus and one element becomes a completely different one, with different color, reactivity, and state. Arvin Ash explains why that one number decides an element's entire personality. The cleanest explanation of what the periodic table is really organizing.

How Do Elements Get Their Physical Properties?
Why is one metal soft and another impossibly hard, one element a gas and its neighbor a solid? This traces those everyday properties back to how electrons arrange themselves around the nucleus. A great companion to the periodic table guide.

Bonds and Reactions
A chemical bond is quantum mechanics in action, and whether a reaction fizzes or explodes comes down to deep rules about how electrons are allowed to share space.
Quantum Physics Does Something Weird When Atoms Touch
Chemistry is really quantum mechanics at the scale of bonding. When two atoms meet, their electron clouds follow quantum rules, and the result is the chemical bond that holds all matter together. A perfect link between this page and our quantum videos.

The Pauli Exclusion Principle Determines if Your Reaction Explodes
A deep quantum rule, the Pauli exclusion principle, sits behind why some reactions are gentle and others violent. Arvin Ash connects that abstract law to the very practical question of what happens when two chemicals meet, which is chemistry at its most satisfying.

Materials That Change Everything
Materials science is where chemistry meets the real world, and these two Veritasium films show how much rests on getting the structure of a material exactly right.
The Perfect Battery Material Is Dangerous
The search for better batteries keeps hitting the same trade-off: the materials that store the most energy are also the most prone to catching fire. Veritasium walks through the real chemistry and engineering behind that tension, which touches every device you own.

The Crystal That Could Destroy All Medicine
The same molecule can crystallize into more than one form, and sometimes a new, more stable form appears that ruins a working drug overnight, everywhere at once. A genuinely unsettling story about how much rests on the hidden structure of crystals.
