  2. Everything around us is made of atoms. So far, scientists have found only _____ different kinds of atoms. Everything you see is made of different combinations of these atoms. 115

  3. PARTS OF AN ATOM • So, of what are atoms made? In the middle of each atom is a _____________. The nucleus contains two kinds of tiny particles, called __________ and ___________. Orbiting around the nucleus are even smaller particles called ____________. nucleus protons neutrons electrons

  4. The 115 kinds of atoms are different from each other because they have different ____________ of protons, neutrons and electrons. numbers Carbon atom Oxygen atom

  5. It is useful to think of a model of the atom as similar to the solar system. The _________ is in the center of the atom like the _____ is in the center of the solar system. The __________ orbit around the nucleus like the ________ around the sun. nucleus sun electrons planets

  6. nucleus Just like in the solar system, the ________is large compared to the electrons. The atom is mostly ______________, and the electrons are very far away from the nucleus. While this model is not completely accurate, we can use it to help us understand static electricity. empty space Empty Space

  7. Protons, neutrons and electrons are very different from each other. They have their own properties, or characteristics. One of these properties is called an __________________. • Protons have what we call a ___________charge. • Electrons have a ____________charge. • Neutrons have ___________; they are neutral. electrical charge positive (+) negative (-) no charge

  8. equal The charge of one proton is ______ in strength to the charge of one electron. When the number of protons in an atom equals the number of electrons, the atom itself has no overall charge; it is _____________. neutral 3 protons + 3 electrons = Neutral Charge

  9. The protons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are held very loosely. They can move from one atom to another. An atom that loses electrons has more positive charges (protons) than negative charges (electrons). It is ____________ charged. positively

  10. An atom that gains electrons has more negative than positive particles. It has a ____________ charge. A charged atom is called an “_________." negative ion

  11. Some materials hold their electrons very tightly. Electrons do not move through them very well. These things are called ____________. Plastic, cloth, glass, and dry air are good insulators. insulators

  12. Other materials have some loosely held electrons, which move through them very easily. These are called ___________. Most metals are good conductors. conductors

  13. How can we move electrons from one place to another? One very common way is to ____ two objects together. If they are made of different materials, and are both insulators, electrons may be transferred (or moved) from one to the other. The more rubbing, the more electrons move, and the larger the static charge that builds up. rub Both objects are neutral Balloon is negatively charged…the hand is positively charged.

  14. imbalance • Static electricity is the __________ of • __________ and _________ charges. negative positive Now, positive and negative charges behave in interesting ways. Did you ever hear the saying that opposites attract? Well, it's true.

  15. Two things with opposite, or different charges (a positive and a negative) will ________ or pull towards each other. attract

  16. Things with the same charge (two positives or two negatives) will ______ or push away from each other. repel

  17. What does that have to do with static electricity in hair? When you take off your hat, it rubs against your hair. Electrons move from your hair to the hat. A static charge builds up and now each of the hairs has the same positive charge. Remember, things with the same charge repel each other. So the hairs try to get as far from each other as possible. Try rubbing a balloon vigorously against your hair. What happens?

  18. As you walk across a carpet, electrons move from the rug to you. Now you have extra electrons and a negative static charge. Touch a door knob and ZAP! The door knob is a conductor. The electrons jump from you to the knob, and you feel the static shock.

  19. We usually only notice static electricity in the ________ when the air is very _____. The air is more humid during the summer. The water in the air helps electrons move off you more quickly, so you cannot build up as big of a static charge. dry winter

  20. REVIEW atoms Everything around us is made of ___________. In the middle of an atom is the ___________. The nucleus is made up of ___________ and ______________. Orbiting the nucleus are the ____________. Electrons have a ____________ charge, and protons have a ____________ charge. nucleus protons neutrons electrons negative positive

  21. electrons When two objects rub together, ___________ can transfer from one of the objects to the other. An atom that loses an electron has a __________ charge; an atom that gains an electron has a ___________ charge. Static electricity is due to the ____________ of positive and negative charges. Two things with opposite charges ___________ while two things with the same charges ________. positive negative imbalance attract repel
