Sub-Atomic Particles

  • Electron
    • Ions are formed when atoms lose or gain them.
      • Positive ions are called cations and negative ones are called anions.
        • Electrons are so small their weight is insignificant to most calculations.
    • Are negatively charged.
    • Neutrons
      • Differing amounts of neutrons but the same amount of electrons and protons are isotopes of an atom.
        • Have no charge, are neutral, so thus the name neutrons.
      • Protons
        • Are positively charged.
          • Are the same amount as the neutrons.
            • Their weight is the same as neutrons and 1837 times heavier than that of electrons,
      • Sub-atomic particles
        • Atoms
          • Atomic mass is the number of protons and neutrons
            • Atomic number is the number of protons in an atom of an element so if you take this away from the atomic mass it would give you the number of protons/ neutrons.
