oneone EEM-5 What do you think is going on? On your dry erase board write 3-5 words that you think might be involved in the explanation.

oneone EEM-5 Types of Electric Charge The charged parts of atoms are electrons and protons. As you have learned, protons and electrons are charged particles. When two protons come close, they push one another apart. In other words, they repel each other. But if a proton and an electron come close, they attract one another. WHAT IS ANY PUSH OR PULL? A FORCE

oneone EEM-5 Why do protons repel protons but attract electrons? The reason is that they have different types of charge. Protons and electrons have opposite charges. The charge on the proton is called positive (+), and the charge on the electron is called negative (−). The names positive and negative were given to charges by Benjamin Franklin in the 1700s. They have been used by scientists ever since.

oneone EEM-5 Interactions Between Charges The two types of charge interact in specific ways. 1.Charges that are the same repel each other. 2.Charges that are different attract each other. 3.Neutral particles have no effect on charged particles. Charged particles can exist without other charged particles!

oneone EEM-5 How far does the effect of charged particles reach? ELECTRIC FIELD – the area around a charged particle affected by its charge
