  • ATOMS
    • Atom contains nucleus.
      • Middle of the atom.
      • Contains protons and neutrons.
      • Positive charge because of protons.
    • Atom contains electrons.
      • Move around the nucleus in electron shells.
      • Negatively charged
      • Tiny but cover a lot of space.
      • No mass
    • Protons, Neutrons and Electrons
      • Protons are heavy and positively charged.
      • Neutrons are heavy and neutral
      • Electrons are tiny and negatively charged.
    • Number  of protons= number of electrons.
      • Neutral atoms have no charge.
      • The charge of the electrons is the same size as the charge on the protons
  • Contains protons and neutrons.
  • Protons, Neutrons and Electrons
    • Protons are heavy and positively charged.
    • Neutrons are heavy and neutral
    • Electrons are tiny and negatively charged.
