The Atom

     - All matter is composed of elements
     - All elements are composed of atoms
     - The atom is composed of:
–Nucleus:   - neutrons    - protons
–Orbital Shell:  - electrons
     - Stable atoms have a balance of protons and neutrons.
     - Radioactive atoms contain excess energy, and the ratio of protons to neutrons is too low or too high
