What Is Hydrogen and Why Is It Important?

TL;DR

Hydrogen, the lightest and most abundant element, is crucial for forming water (H2O) and has significant implications in chemistry through its isotopes, Deuterium and Tritium. Deuterium, which has one neutron alongside its proton, results in different chemical behaviors than regular hydrogen, while Tritium is radioactive, underscoring hydrogen's diverse roles in science and energy.

Match on a stick to hydrogen. Big bang coming. Ready? yep, here we go... Hydrogen it the lightest element. And it's also a very abundant element. You find it throughout the universe. It's in stars, in the space between stars, and of course on Earth. So here is our little Hindenburg, yes? A nice shinny balloon with a very very flammable coating. We... Read More
