Charge

• What is charge in relation to matter?

  Charge is a property of matter that affects electrostatic forces.
• How is charge described in terms of its nature?

  Charge is intrinsic and occurs naturally, similar to mass.
• Which subatomic particles have charge?

  Almost all subatomic particles have charge, such as protons and electrons.
• What type of charge does a proton have?

  A proton has a positive charge.
• What type of charge does an electron have?

  An electron has a negative charge.
• What does charge give rise to between particles?

  Charge gives rise to a force between particles.
• What is the electrostatic force?

  The electrostatic force is a force of attraction between particles with opposite charges.
• What charge do neutrons have?

  Neutrons have no charge.
• What do you need to know about electrostatic forces for your exam?

  You only need to know that we see electrostatic forces between charged objects like protons and electrons.
• In what unit is charge measured?

  Charge is measured in coulombs (C).
• What is the charge of a proton in coulombs?

  A proton has a charge of $+$$1.6 \times 10^{-19} \text{ C}$.
• What is the charge of an electron in coulombs?

  An electron has a charge of $-1.6 \times 10^{-19} \text{ C}$.
• How do the charges of protons and electrons compare?

  The charges of a proton and an electron are equal and opposite.
• What is the overall charge of an atom?

  An atom has a charge of zero coulombs as the charges cancel out.
