Lepton

A lepton is a tiny, tiny thing that scientists use to understand how everything in the universe works. Just like how people use Lego blocks to build big structures, scientists use leptons to build atoms and particles.

There are six different types of leptons, but the most common ones are called electrons. You might have heard of those before - they're the things that make TVs and computers work!

Leptons are very light and don't have any charge, which means they don't stick to things like a magnet. But even though they're so small, they're important because they make up everything around us, like the air we breathe and even our own bodies.

Scientists study leptons to learn all sorts of things about the world. They can use them to understand how particles interact with each other and how energy is transferred. They can also use them to create exciting new technologies that help us live better lives.
