Name _____________________ Period _______ Static Electricity Quiz Sometimes objects have electric charge, causing interactions between particles. Objects get those charges from atoms! 1. Label the basic parts of an atom: 2. Match the subatomic particle to its corresponding charge: Proton Neutral Electron Positive Neutron Negative 3. Which subatomic particle can be gained or lost (causing charges)? ________________________ 4. Atoms are balanced if they have the same number of ___________________ and ___________________. The ratio of protons to electrons determines the charge of an atom. Circle the best answer to complete the sentences below. 5. Atoms with more electrons than protons are ____________ charged. a. positively b. negatively 6. Atoms with more protons than electrons are ____________ charged. a. positively b. negatively When different charges interact they behave differently. Based on the interaction below, circle if the particles will repel or attract each other. 7. Two of the same charge Attract or Repel 8. One negative and one positive charge Attract or Repel Circle if the statements below are true or false: 9. True or False Electrical force weakens with distance. 10. True or False The law of conservation of charge states that a charge cannot be created or destroyed, it can only be transferred. There are three ways charges are transferred. Match each vocabulary word to their definition: Word bank Friction Direct Contact 11. ____________________ Two objects rubbed together causes electrons to jump from one to the other. 12. ____________________ Charges can be transferred by touching an object. BONUS (optional) Induction is when an object with charge comes near another object, causing a separation of charges in the neutral object. Using pictures and/or words, demonstrate what this looks like. (Think about the video demonstration from yesterday) 15 points total; 17 points possible
