Electrical Charges

    Cards (11)

    • All matter consists of atoms
    • Subatomic particles in atoms
      • Protons
      • Neutrons
      • Electrons
    • Protons
      Subatomic particle with a positive charge and a relative mass of 1
    • Neutrons
      Uncharged subatomic particle, with a mass of 1 relative to a proton
    • Electrons
      Subatomic particle, with a negative charge and a negligible mass relative to protons and neutrons
    • Charge
      Property of matter that causes a force when near another charge. Charge comes in two forms, positive and negative.
    • Protons are positively charged. Electrons are negatively charged.
    • Non-contact forces
      Forces exerted between two objects, even when they are not touching, such as the force of gravity
    • Static electricity
      Electric charge that accumulates on an insulated object, for example because of friction
    • Generally, the atom has a neutral charge, but if it loses an electron, it becomes positively charged and if the atom gains an electron, it becomes negatively charged
    • Ions
      Charged atoms
