  1. Name the three subatomic particles of an atom and identify thier charge.
    • Protons are positive
    • Neutrons are neutral
    • Electrons are negative
  2. Name the three subatomic particles of an atom and state thier mass.
    • Proton mass is 1 amu
    • Neutron mass is 1 amu
    • Electrons have no mass
  3. What is the charge of the nucleus of an atom?
    Positive
  4. Atoms, as listed on the periodic table, have what charge?
    Atoms are electrically neutral
  5. How does one calculate the number of neutrons in an atom?
