  • Charge is a property of matter affecting electrostatic forces.
  • Charge is intrinsic and occurs naturally, similar to mass.
  • Almost all subatomic particles have charge.
  • Protons have a positive charge; electrons have a negative charge.
  • Charge gives rise to a force between particles, known as electrostatic force.
  • Electrostatic force is an attraction between particles with opposite charges.
  • Neutrons have no charge.
  • Electrostatic forces are observed between charged objects like protons and electrons.
  • Charge is measured in kloss.
  • A proton has a charge of +1.6 x 10^-19 kloss.
  • An electron has a charge of -1.6 x 10^-19 kloss.
  • The charges of a proton and an electron are equal and opposite.
  • Protons have a positive charge; electrons have a negative charge.
  • An atom has a charge of zero kloss as the charges cancel out.
