Electric Vocabulary

What I have learned about electricity so far is that there are three types of charges , Positive, negative, and neutral charges . A positive charges are called a protons, negative charges are called elctrons and neutral charges are called neutrons. I also learned about conductors and insulators. A conductor allows electrons or electricity to flow freely and an insulator doesn't allow electrons or electricity to flow freely. A final thing I learned is that opposite charges attract and the same charges repel.
