We already know what matter is made up of. Guess? Yep you guessed
it…ATOMS. Like a house made up of bricks all matter is made up of bundles
of atoms that could be the same or different. But you see even bricks
are made up of smaller stuff right? And guess what, so are atoms. Some of
the small particles that make up atoms are called electrons, and protons.
What is so interesting about these particles is that they have charge. The
charged electrons are especially important when we talk about electricity.
Especially electrons they are all charged up!
