The flashcards below were created by user Risette on FreezingBlue Flashcards. What would you like to do?


  1. atom
    the smallest particle of a chemical element that retains the structural properties of that element
  2. proton
    a fundamental particle in the structure of the nucleus of an atom; possesses a positive charge
  3. neutron
    a fundamental particle in the structure of the nucleus of an atom; possesses a neutral charge
  4. electron
    a negatively charged fundamental particle that orbits around the nucleus of an atom
  5. nucleus
    the central part of an atom; composed of protons and neutrons
  6. centrifugal force
    force that moves away from the center; for example, the circular motion of electrons spinning around a nucleus generates centrifugal force
  7. valence shell
    the outermost plane of orbiting electrons in the structure of an atom
  8. free electron
    an electron that has broken away from its "home" atom to float free
  9. electrical current
    the flow or movement of electrons through a conductor
  10. ampere
    the unit of measurement of electrical current
  11. potential
    the difference in electrical charge between two bodies; measured in volts
  12. volt
    the unit of measurement of electrical potential
  13. source
    the origin of electrical potential, such as a battery or 120-volt wall outlet
  14. load
    a device that converts electrical energy into another form of energy: a lamp that converts electrical energy to light and heat; an electrical motor converts electricity to mechanical energy
  15. resistance
    the opposition to electron flow within a conductor, measured in ohms; the amount of the resistance is dependent on the chemical makeup of the material through which the electricity is flowing
  16. fuse
    a device to protect a circuit from an overload; has a soft metal strip that melts, breaking circuit continuity
  17. circuit breaker
    a device to protect a circuit from an overload; has a magnetic device that trips open, breaking circuit continuity
