Atomic Structure 6 Objective: Students will be able to examine the parts of an atom in order to be able to demonstrate how to determine which groups of elements form cations and which form anions 1. What will we learn today? _____________________________________ _____________________________________________________________ 2. How will you learn this? ______________________________________ _____________________________________________________________ 3. List the parts of an atom and tell how you would determine them from information found in the periodic table of elements for each atom 4. Write the isotopic symbol for the following atoms IRON-56 + COPPER-66 + NITROGEN-16 + CARBON-14 5. Tell which of the above examples are isotopes of their atom, explain how you know. ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ 6. How could you determine the number of neutrons in an atom or an isotope? ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ 7.
