Electric Charge

    Cards (7)

    • What’s are the charge of a particles?
      -The charge of a particle is either:
      • Positive
      • Negative
      • Neutral (no charge)
    • What are atoms made from?
      -Electrons are negatively charged particles, whilst protons are positive and neutrons are neutral
    • What is an atom neutral?
      -in a neutral atom, the number of electrons is equal to the number of protons
      • This is so the equal (but opposite) charges cancel out to make the overall charge of the atom zero
    • when does an object become negatively charged?
      -Therefore, an object becomes negatively charged when it gains electrons and positively charged when it loseselectrons
    • what occurs when two charged particles are close together?
      -When two charged particles or objects are close together, they also exert a force on each other
    • What are the two forces a 2 charged particle would exert?
      • Attractive (the objects get closer together)
      • Repulsive (the objects move further apart)
    • What determines whether two objects attract or repel?
      -Whether two objects attract or repel depends on their charge
      • If the charges are the opposite, they will attract
      • If the charges are the same, they will repel
