The Charge of Particles

The Charge of Particles

  1. A neutral atom contains the same number of electrons as the protons.
  2. The positive and negative charges of the protons and electrons respectively neutralise each other, for example, (+4) + (-4) = 0
  3. If the number of protons is greater than the number of electrons, the particle is positively charged.
  4. If the number of protons is greater than the number of electrons, the particle is positively charged.
