  1. Dispatch #9 Draw a Carbon atom.

  2. Dispatch # 8 List some examples of chemical reactions: Burning Fizzing Color change with iodine Giving off heat Change in pH When atoms/elements exchange electrons with other atoms, a chemical reaction occurs.

  3. Dispatch # 7 Why do atoms/ elements react? Atoms react when their last energy level is not complete. These are called valence electrons.

  4. Dispatch #6 How are elements arranged on the periodic table? Why is the shape of the periodic table peculiar (strange)?

  5. Dispatch #6 How are elements arranged on the periodic table? By atomic number Why is the shape of the periodic table peculiar (strange)? The elements line up in families by how they will react– dependent on the number electrons on the last energy level

  6. Dispatch #5 Why do elements react with other elements? When elements do not have a full last energy level, they will react with other elements to form compounds. When they react they share or give away electrons.

  7. Dispatch : #4 The number of electrons in the _____ _____ level determines the characteristics of the atom! They are called valence electrons.

  8. Dispatch #3 The atomic number is equal to the number of _________________ or ______________. This number is unique for every element. The atomic mass is equal to the amount of ______________ added to the number of _________________.

  9. Dispatch #2 What are the parts of an atom?

  10. New Unit: Dispatch #1 Solve the Riddle: What is so small we can’t see it, yet it is filled with mostly empty space?
