Subatomics Review:

• The Atom:

  • “Building Blocks” of matter

  • The smallest unit of matter that defines a particular element

  • Nutural atoms have the same amouth of protons and electrons

  • mass of the atom is in the nucleus

• The Elcectron:

  • Locted outside of the Nuclus (electron cloud)

  • Negitive charge (-1)

  • small compared to protons and nutrons (m&m next to a basketball)

  • involved in bonding

• Electron Cloud:

  • an area NOT a substance

  • surrounds the nucleus

  • electrons located here, mostly close to the nucleus

• The Nucleus:

  • Core of the atom

  • contains almost all the mass of the atom

    • Proton:

      • in nucleus

      • positive charge (+1)

      • the number of protons defines the element (atomic number)

    • Neutron:

      • in nucleus

      • no charge (neutral)

      • Mass of 1 AMU (Atomic Mass Unit)

      • Add to mass of atom

        Atoms that have the same number of protons but different numbers of nutrons are isotopes
